Published: September 2023

Recent work inDrosophilahas uncovered several neighboring classes of sleep-regulatory neurons within the central complex. However, the logic of connectivity and network motifs remains limited by the incomplete examination of relevant cell types. Using a recent genetic–anatomic classification of ellipsoid body ring neurons, we conducted a thermogenetic screen in female flies to assess sleep/wake behavior and identified two wake-promoting drivers that label ER3d neurons and two sleep-promoting drivers that express in ER3m cells. We then used intersectional genetics to refine driver expression patterns. Activation of ER3d cells shortened sleep bouts, suggesting a key role in sleep maintenance. While sleep-promoting drivers from our mini-screen label overlapping ER3m neurons, intersectional strategies cannot rule out sleep regulatory roles for additional neurons in their expression patterns. Suppressing GABA synthesis in ER3m neurons prevents postinjury sleep, and GABAergic ER3d cells are required for thermogenetically induced wakefulness. Finally, we use an activity-dependent fluorescent reporter for putative synaptic contacts to embed these neurons within the known sleep-regulatory network. ER3m and ER3d neurons may receive connections from wake-active Helicon/ExR1 cells, and ER3m neurons likely inhibit ER3d neurons. Together, these data suggest a neural mechanism by which previously uncharacterized circuit elements stabilize sleep–wake states.
Risible: Laughter without Reason and the Reproduction of Sound
Authors: Casadei Delia
Published: September 2023

Risible explores the forgotten history of laughter, from ancient Greece to the sitcom stages of Hollywood. Delia Casadei approaches laughter not as a phenomenon that can be accounted for by studies of humor and theories of comedy but rather as a technique of the human body, knowable by its repetitive, clipped, and proliferating sound and its enduring links to the capacity for language and reproduction. This buried genealogy of laughter re-emerges with explosive force thanks to the binding of laughter to sound reproduction technology in the late nineteenth century. Analyzing case studies ranging from the early global market for phonographic laughing songs to the McCarthy-era rise of prerecorded laugh tracks, Casadei convincingly demonstrates how laughter was central to the twentieth century’s development of the very category of sound as not-quite-human, unintelligible, reproductive, reproducible, and contagious.

The study revealed specific features in the everyday life informatization, morphofunctional and motor development of 5th grade students with high and low levels of general and strength endurance. In this study, boys with a high level of general and, to a lesser extent, strength endurance demonstrated a better, as compared with peers with a low level of the motor abilities, reserve of the autonomic system against the background of a shift in the autonomic balance towards a predominance of the parasympathetic system. This group of children had the best morphofunctional and motor development. The results obtained suggest that physical exercises aimed at increasing general and strength endurance can help optimize the use of digital technologies and electronic devices by 11–12-year-old students and have a beneficial effect on their morphofunctional and motor development in today’s information and educational environment.

Authors: Bajuk Studen Katica , Gaberšček Simona , Pirnat Edvard , Bedernjak Bajuk Nataša , Vendramin Andreja , Majcen Vito , Zaletel Katja
Published: September 2023

Objective

The optimal corticosteroid treatment regimen for subacute thyroiditis has not yet been established. To avoid side effects, tapering of the initial dose of corticosteroid is recommended. With reducing dose, the symptoms can recur.

Design

In a prospective clinical study, a 30-day methylprednisolone (MPSL) treatment protocol with a starting dose of 24 mg/day and tapered by 4 mg every 5 days was assessed for effectiveness and safety regarding possible adrenal insufficiency.

Methods

Fifty-nine patients with subacute thyroiditis were included. At visit 1, after establishing the diagnosis, a short stimulation adrenocorticotrophic hormone (ACTH) test was performed and methylprednisolone treatment was prescribed. At visit 2 (40 ± 5 days after visit 1), clinical, laboratory (including short stimulation ACTH test), and ultrasound evaluation were repeated.

Results

Forty-eight patients (81.4%) were cured by the prescribed protocol, having significantly lower cortisol levels after stimulation at visit 1 than patients who were not cured (mean, 674.9 nmol/L and 764.0 nmol/L, respectively, P = 0.012). Seven patients (12.3%) developed adrenal insufficiency; this group had significantly lower cortisol levels after stimulation at visit 1 than patients without adrenal insufficiency development (mean, 561.5 nmol/L and 704.7 nmol/L, respectively, P = 0.005). Using stimulated cortisol level at visit 1 as the explanatory variable, logistic models were optimized to determine treatment efficacy (AUC = 0.745, optimal threshold 729 nmol/L, specificity 71%, sensitivity 73%) and adrenal function (AUC = 0.861, optimal threshold 629 nmol/L, specificity 73%, sensitivity 100%).

Conclusions

The described protocol was efficient for more than 80% of patients. Using this protocol, the corticosteroid treatment interval is shorter than proposed in current guidelines.

Significance statement

A short but effective protocol for treatment of subacute thyroiditis with methylprednisolone is presented in this article. Using this protocol, the treatment interval is shorter than proposed in current guidelines. Its safety regarding possible adrenal insufficiency is assessed.

Authors: Leguizamon Griselda
Published: September 2023

Este trabajo tiene como propósito identificar, describir e interpretar las formas en que los estudiantes de carreras de formación docente construyen saberes pedagógicos tomando como eje de investigación el espacio de la práctica docente en la formación inicial del profesorado. Esta investigación fue abordada con una metodología cualitativa utilizando instrumentos de recogida de información como la entrevista semi-estructurada aplicada a practicantes y profesores de la muestra seleccionada. En adición a las técnicas mencionadas, se recolectaron y analizaron documentos narrativos tales como: diarios y relatos o textos pedagógicos, autobiografías, planificaciones de clase y auto y co-evaluaciones, elaborados por los practicantes. Se analizan los distintos modos en que se expresa la construcción de saberes pedagógicos durante el proceso de la formación inicial, distinguiendo los saberes teóricos de los saberes prácticos para interrogarnos luego, sobre los posibles cruces entre ambos tipos de saberes en la configuración de las prácticas cotidianas.

Authors: Adrogué de Deane Cecilia , Corengia Ángela , García de Fanelli Ana , Pita Carranza María
Published: September 2023

El desarrollo de la actividad de investigación ha sido débil en gran parte de las instituciones universitarias argentinas, principalmente en las de gestión privada. Frente a esto, se generó un entorno de políticas públicas para impulsar su desarrollo. En este trabajo se analiza en qué medida las regulaciones, señales e incentivos generados por estas políticas han favorecido al aumento en la actividad de investigación en el sector universitario privado. Para ello se analizó la evolución de un conjunto de indicadores de insumos y resultados de I+D y se realizó un análisis de conglomerados para clasificar las instituciones en grupos. Los resultados evidencian que el nuevo entorno de las políticas públicas analizadas favoreció el aumento de la actividad de investigación. Se concluye que si bien todas las instituciones universitarias privadas enfrentaron las mismas regulaciones e incentivos, sus respuestas estuvieron mediadas por la heterogeneidad de sus misiones, estrategias organizacionales y campo disciplinar.

Authors: Sun Jinping , Leithwood Kenneth
Published: September 2023

Este estudio, basado en la síntesis de una investigación inédita sobre liderazgo transformacional en la escuela (LTE) realizada en los últimos catorce años, aborda la naturaleza del LTE y sus efectos sobre el logro de los estudiantes empleando métodos de revisión que incluyen un meta-análisis estándar y técnicas de recuento. Los resultados muestran un amplio espectro de prácticas de LTE que han sido medidas en investigaciones previas, sugieren que el LTE tiene un pequeño pero significativo efecto en el logro de los estudiantes y que algunas prácticas de LTE son explicaciones poderosas de estos efectos. También se ha demostrado que un número importante de variables hacen de moderadores y mediadores de los efectos del LTE sobre los estudiantes.
Mantener el Cambio: Lo que Significa el Desarrollo de Capacidades en la Práctica
Authors: Day Christopher
Published: September 2023

El propósito de este artículo es mostrar cómo centros en contextos urbanos de comunidades altamente desfavorecidas, logran y mantienen la mejora escolar, apoyándose en las cualidades y competencias de sus directores para implicarse simultáneamente en la construcción de las capacidades individuales, colectivas y de la comunidad. Las definiciones de la construcción de capacidades como “la interacción entre las habilidades personales, las relaciones interpersonales y las estructuras organizativas” (Mitchell y Sackney 2009:11) son limitadas en la puesta en práctica dado que frecuentemente fallan en el reconocimiento de que a lo largo del paso del tiempo se necesita construir entornos estables de aprendizaje y de rendimiento; los directores probablemente han de atravesar diferentes capas en las fases de desarrollo, cada una ellas tienen sus propias prioridades; y durante estos procesos de cambio, los directores probablemente también necesitan mantener, articular y comunicar una serie de valores claros en los que se basan sus estrategias.
La Formación de Directores. Un Modelo Centrado en el Análisis de las Prácticas
Authors: Nicastro Sandra
Published: September 2023

La formación de directores tiene una vasta experiencia tanto en nuestro país como en el extranjero. En este artículo se presentan algunas reflexiones acerca de un modelo de formación centrado en el análisis de las prácticas del director contextualizándolas en la organización escolar y sus condiciones y en una trama que combina lo comunitario, lo social, lo político y lo cultural. Para ello la reflexión se focaliza sobre las posiciones de los sujetos en las organizaciones, el espacio escolar, el tiempo e historia institucionales, la cultura y modos habituales de definir y abordar las situaciones propias del trabajo directivo. Se presentan algunas experiencias llevadas a cabo en el marco de un dispositivo de formación que desde una perspectiva institucional propone un encuadre que privilegia el reconocimiento de la dimensión institucional del trabajo del director en las organizaciones educativas.
As Lideranças e os Processos Participativos: Uma Reflexão em Torno da Cidadania
Authors: Fraga Nuno
Published: September 2023

O presente artigo reflete sobre o potencial das lideranças na gestão estratégica do espaço público, em particular a partir das dinâmicas concertados do poder local com a comunidade. Propomos uma reflexão teórica sobre os estilos de liderança fundamentados no pensamento de Daniel Goleman, convergindo para a necessidade de compreender tais pressupostos na praxis de uma líder autárquica. O estudo de caso pretendeu compreender os canais de comunicação entre líder e liderados e daí contextualizar a importância deste referencial teórico na condução de processos participativos no espaço local; a sua relação com a cidadania democrática, bem como o lugar da educação na encruzilhada de uma democracia possível. Concluímos que as questões de partilha de poder e/ou delegação de competências interferem com a real abertura dos atores sociais no decorrer dos processos participativos, sendo necessário repensar a liderança de proximidade como fator crucial ao sucesso destas práticas.
Mejora de la Escuela: Medio Siglo de Lecciones Aprendidas
Authors: Murillo F. Javier , Krichesky Gabriela J.
Published: September 2023

El fracaso de las reformas curriculares de los años 60 y de lo inútil de las innovaciones impuestas “de arriba a abajo” hicieron que se volviera la mirada a la escuela como el centro del cambio educativo, con lo que se inició el Movimiento teórico-práctico de Mejora de la Escuela. El presente artículo, en primer lugar, hace un repaso a la evolución de esta línea, deteniéndose en las diferentes etapas por las que ha transitado y en sus características definitorias. En segundo lugar, se centra en las lecciones aprendidas en estas décadas que pueden ser útiles para la puesta en marcha de procesos de transformación escolar en la actualidad. Concretamente se abordan seis grandes aspectos: la colaboración docente y el trabajo en redes, la implicación de la comunidad, el liderazgo sistémico, la centralidad de los procesos de enseñanza y aprendizaje, el debate entre la responsabilidad y la rendición de cuentas, y las nuevas relaciones entre la administración pública y las escuelas. Para finalizar se aborda el para qué del cambio: una educación para la justica social.

Published: September 2023

Uno de los aspectos de mayor importancia al evaluar la calidad organizacional es evaluar la satisfacción de los usuarios. Los estudiantes al ser los principales usuarios de las Universidades, serán quienes mejor puedan evaluar la calidad de los servicios educativos. Se diseñó y aplicó un instrumento a estudiantes del Valle de Toluca, de Universidades públicas y privadas. En base a escala Likert los estudiantes calificaron aspectos como Plan de estudios, Habilidad para enseñanza docente, Métodos de enseñanza-evaluación, Nivel de autorrealización del estudiante, Servicios de apoyo, Servicios administrativos, Ambiente propicio e Infraestructura. Como resultado se concluye que las variables donde se encuentran mayormente satisfechos son: Habilidad para la enseñanza de los Docentes y nivel de Autorrealización de Estudiantes. En cambio, las variables Infraestructura y Servicios Administrativos obtuvieron niveles de satisfacción inferior. La prueba Chi-cuadrado confirma diferencias significativas entre Universidades públicas y privadas las cuales serán presentadas en este reporte de investigación.
Definiendo Identidades: el “Canciograma” como Herramienta Metodológica de Autoconocimiento
Authors: Colomo Ernesto , Domínguez Martín Rosa
Published: September 2023

Este trabajo presenta los resultados de un estudio sobre el papel de las canciones en diferentes aspectos de nuestra identidad. Se ha llevado a cabo mediante la elaboración, análisis e interpretación de relatos autobiográficos (canciogramas). Pretendemos analizar el papel de la música centrándonos en el proceso de (re)construcción de quiénes somos a partir de los momentos/experiencias que dejan huella y tenemos asociados a canciones. De esta manera valoraremos la posibilidad de utilizar las mismas como recursos didácticos para trabajar el vínculo existente entre música e identidad en los ámbitos educativos formales, no formales e informales. Se ha utilizado una metodología cualitativa de corte narrativo, profundizando en la investigación biográfica. A través de historias de vida percibiremos la incidencia de la música en nuestra forma de pensar, sentir y actuar sobre ciertos temas y realidades (amor, desamor, muerte, ocio, entre otros) interpretando el sentido y significado de las canciones como medio de comunicación a la hora de conocernos mejor, desarrollarnos y progresar como seres humanos mediante un proceso reflexivo y analítico sobre nuestro yo.

Published: September 2023

Die kartellrechtliche Missbrauchsaufsicht hat zuletzt in der Digitalwirtschaft mit dem Inkrafttreten des Digital Markets Act einem stärker regulierungsrechtlich ausgerichteten Ansatz Platz machen müssen. Mit einer Reihe wichtiger Gerichtsentscheidungen auf Unionsebene „meldet“ sich Art. 102 AEUV „zurück“. Dieser Beitrag berichtet in einem Rückblick auf die letzten 18 Monate von sechs Entscheidungen aus Luxemburg, die die kartellrechtliche Missbrauchsaufsicht spürbar weiterentwickeln. Dabei fällt auf, dass – anders als für die nationale Kartellgesetzgebung prägend – es keineswegs nur um eine „Verschärfung“ der Missbrauchsaufsicht geht. Vielmehr loten die Entscheidungen sowohl Fehler erster Art (zu früher Eingriff) und Fehler zweiter Art (zu später Eingriff) aus, so dass sich in der Gesamtschau neue Anforderungen, aber auch neue Spielräume für marktbeherrschende Unternehmen ergeben.

Published: September 2023

Die erste Entscheidung des UK Competition Appeal Tribunal zum LKW-Kartell bietet wertvolles Anschauungsmaterial für die zivilrechtliche Aufarbeitung von Kartellverstößen und für die dabei im Mittelpunkt stehende Schadensberechnung. Die Entscheidung zeigt exemplarisch das Spannungsverhältnis zwischen Präzision und Pragmatismus auf, das die Gerichte vor dem Hintergrund bestehender Erkenntnisgrenzen und daraus resultierender Unsicherheit aufzulösen haben. Das Tribunal schätzt den kartellbedingten Preisaufschlag auf Grundlage qualitativer Plausibilitätserwägungen und ökometrischer Berechnungen auf 5 Prozent der kartellierten Umsätze und weist sämtliche Einwände zur Vorteilsausgleichung zurück, wobei die Streuschadenproblematik nicht zuletzt wegen des vorliegenden Minderheitsvotums von besonderem Interesse ist.

The principles of operation and a static simulation model of the power-generating equipment of the autonomous power supply source based on a hydroelectric unit with a 275 kVA induction generator and a combined capacitor-inverter excitation system supplying a symmetrical passive load have been developed. The initial excitation of the generator is carried out by a bank of capacitors of the initial excitation. During low power demand the generator voltage is kept constant by adjusting the reactive power of the semiconductor converter, and at high loads, the voltage is adjusted as a result of the switching of additional capacitor banks. The developed methodology for performance analysis the pro-posed power supply source is based on the IG equivalent circuit. Computations of the static characteristics of the gen-erator operating with a constant rotor speed were carried out and the obtained static characteristics were analyzed for two set values of the load power factor.

This paper is devoted to the problems of developing an electric machine with two-degrees-of-freedom (2-DOF) of rotor movement and its control system. The structure of the machine with the possibility of rotation of the rotor along two angular coordinates in a limited range of rotation angles is considered. The machine is designed to control the position of the axis of the optical beam along the line and frame trajectories. Based on the electrodynamic state model of the 2-DOF electric machine, a block diagram of the servo system was developed to control the trajectory of the rotor in two coordinates. Relationships between the time constant of the angle controller and the time constants of the high-frequency part of the amplitude-frequency characteristic of an open-loop system are determined. The dependences of the effective values of the currents in the control windings on the frequency of the frames and the duration of the linear part of the triangular signal are obtained. The dependences of the modules of relative accuracy of the rotor movement along a given trajectories on the system tunings are obtained. Ref. 12, fig. 8.

Effect of pituitary adenylate cyclase-activating polypeptide supplementation, applied during or after vitrification on mouse embryo
Authors: Török Dóra , Somoskői Bence , Bordás Lilla , Reglődi Dóra , Cseh Sándor
Published: September 2023

Pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuropeptide with widespread occurrence and diverse functions. It occurs in high levels in the gonads suggesting a potential central role in reproduction. The aim of our study was to assess the effect of PACAP treatment during embryo vitrification on the developmental rate and the expression of the heparin-binding EGF-like growth factor gene (Hbegf). Mouse embryos, obtained from superovulated females were allocated into the four treatment groups. In EM1 and EM2, the embryos were prepared for vitrification in an Equilibration Solution that was supplemented with 1 or 2 μM PACAP1-38, respectively. The embyos in groups CM1 and CM2 were not treated prior to vitrification but were cultured in a medium supplemented with 1 or 2 μM PACAP1-38 after thawing. The Vitrified Control group consisted of embryos vitrified and thawed then cultured without PACAP1-38 treatment. A non-vitrified, non-treated Fresh Control group was also used. After 24 h of culture, the developmental rate of the embryos, as well as the relative expression level of the Hbegf gene, as determined by qPCR, were compared among groups. Higher developmental rate and Hbegf gene expression level were found in the embryos treated with a higher concentration of PACAP. These results indicate that PACAP treatment has a beneficial effect on the survival and development of vitrified/thawed mouse embryos.
Technomad: Global Raving Countercultures
Authors: St John Graham
Published: September 2023

A cultural history of global electronic dance music countercultures, Technomad explores the pleasurable and activist trajectories of post-rave culture. The book documents an emerging network of techno-tribes, exploring their pleasure principles and cultural politics. Attending to sound system culture, electro-humanitarianism, secret sonic societies, teknivals and other gatherings, intentional parties, revitalisation movements and counter-colonial interventions, Technomad investigates how the dance party has been harnessed for transgressive and progressive ends – for manifold freedoms. Seeking freedom from moral prohibitions and standards, pleasure in rebellion, refuge from sexual and gender prejudice, exile from oppression, rupturing aesthetic boundaries, re-enchanting the world, reclaiming space, fighting for “the right to party,” and responding to a host of critical concerns, electronic dance music cultures are multivalent sites of resistance. Drawing on extensive ethnographic, netographic and documentary research, Technomad details the post-rave trajectory through various local sites and global scenes, with each chapter attending to unique developments in the techno counterculture: e.g. Spiral Tribe, teknivals, psytrance, Burning Man, Reclaim the Streets, Earthdream. The book offers an original, nuanced theory of resistance to assist understanding of these developments. This cultural history of hitherto uncharted territory will be of interest to students of cultural, performance, music, media, and new social movement studies, along with enthusiasts of dance culture and popular politics.

Published: September 2023

This research is an analysis of a unique high-density honeycomb foam named Lantor Soric, a flexible core material specifically used for resin infusion. To understand the full scope of this unique core material, it was bonded with various synthetic, natural, and hybrid face sheets. The glass, carbon, and jute fibers were utilized to prepare the face sheets, and epoxy was used as a binder. The sandwich composite samples were developed by a vacuum resin infusion technique. The performance of the sandwich composite, such as water absorption, flammability, and tensile and flexural strength, revealed that the addition of honeycomb foam to the composite structure improved the performance, such as water absorption, flammability, and tensile and flexural strength of the sandwich composite. The honeycomb foam was able to distribute the resin evenly throughout the laminate via its flow channels. Also, the hybrid composite of natural and synthetic fibers showed some astonishing properties in mechanical testing. The failure mechanism of the sandwich composite was inspected using scanning electron microscopy. Fractography revealed that the main mechanism for the failure was fiber pull out, voids, and interfacial debonding.

Due to the high rate of rotator cuff re-tear there is an extensive research on augmentation of rotator cuff repairs. The purpose of this single center, prospective study was to evaluate the results of augmentation of the rotator cuff repair with an umbilical cord allograft. The graft group in which the rotator cuff repair was augmented with the graft as an on-lay patch was consisted of 14 patients, while the control group was consisted of 10 patients. The primary outcome of the study was incidence of rotator cuff retears, while secondary outcomes included functional and pain scores. At 6 mo there was a significantly higher incidence of retears in the control group (30%) compared to the graft group (0%; P = 0.028), while at 12 mo the retear rates were statistically similar for the two groups (P = 0.46). The Constant-Murley scores, the ASES scores and the VAS score were similar (P > 0.05) for the two groups at all study times. The results of the study indicated that augmentation of the cuff repair with human umbilical cord graft can result in similar patient reported outcomes compared to a cuff repair without augmentation, but with a lower re-tear rate at 6 mo.

Introduction: Children with physical disabilities often present deficient oral hygiene and eating habits that threaten optimal oral health. Objective: To evaluate the result of a preventive program based on multiple intelligences to pro-mote oral health care in children with physical disabilities in Chiclayo - Peru. Materials and Methods: A quasi-experimental, quan-titative, prospective and longitudinal study was carried out from the year 2020, to test a preventive intervention based on multiple intelligences (MI), comparing it with an intervention with traditional methodology, whose purpose was in both cases promote preventive oral health care in 167 boys and girls with physical disabilities from four Special Basic Education Centers (CEBES) in Chiclayo. For the pre- and post-test evaluation using a dental record of oral hygiene practices, oral hygiene index and dietary exposure to sugary carbohydrates, the Mann Whitney U test was required, with a confidence level of 95%. Results: After not very encouraging findings in the pretest for both groups, significant changes were observed in the posttest in favor of the IM-based program, for which 58% of schoolchildren registered an adequate oral hygiene index, 69.2% brushed twice to three times a day and that only 35.8% present regular exposure to carbohydrates. Statistical significance was evidenced in favor of the MI-based intervention for the three indicated variables (p= 0.000). Conclusions: The application of the IM-based program achieved better results in the significant promotion of oral hygiene practices with a favorable record of the IHO and by reducing the exposure to carbohydrates in a vulnerable population.

Authors: KAPROL Timur
Published: September 2023

Aim: Çorlu Military State Hospital, which was constructed in the modernist era in Türkiye, has been proven to be authentic by DOCOMOMO Türkiye. Method: First of all, the need for hospital buildings in our country in the years when the building was built was discussed. The importance of the hospital, the health units it contains, within the scope of the architectural appreciation observed in the buildings and its comparative analysis with periodical buildings in our country were made after the literature review. In the study, the survey and restitution projects of the hospital building were used. Results: The advantages brought to architecture by the innovations that the university reform brought both to the medicine and architecture after the establishment of the Republic have been analysed in terms of the contribution of scientists who came to our country after the political events in the West. One of the innovative buildings constructed, similar to particularly the ones in Ankara, Çorlu Military State Hospital is concluded to be an important document of its era in Trakya. For this reason, it has been concluded that it is indispensable for the city’s history and for the survival of social memory. Conclusion: In terms of Historical, Vital, and Stylistic Use, Urban Landscape, Authenticity, Technique and Technology, Integrity, and Group Values, it was concluded that the building should be transferred to future generations.

Quantitative analyses of the ultrastructural features of dopaminergic axon terminals. Protocol #1: Tissue preparation for electron microscopy v2
Authors: M Doig Natalie
Published: September 2023

The release of dopamine from axons is critical for normative brain function and behaviour. Impaired or otherwise inappropriate dopamine release often correlates with changes in the ultrastructure of dopamine neuron axons that can assessed with electron microscopy. Here, we provide two protocols that can be used serially to, first, help the user process animal brain tissue for electron microscopy and, secondly, help the user undertake quantitative analyses of the ultrastructural features of dopaminergic axon terminals in the brain. This Protocol #1 describes how to prepare brain tissue, carry out pre-embedding immunohistochemistry for tyrosine hydroxylase as a marker of dopaminergic axons, and then make tissue sections ready for electron microscope. The partner Protocol #2 details how to examine and image ultrathin sections of tissue using a transmission electron microscope and then how to analyse the digital images. Protocol #1 and #2 are part of the collection "Quantitative analyses of the ultrastructural features of dopaminergic axon terminals". In this new version, the last step contains a supplemental video with extra context and tips, as part of the ASAP Protocol Particulars, featuring conversations with protocol authors
