title: Neural and behavioral data from: A dynamic sequence of visual processing initiated by gaze shifts

description: Animals move their head and eyes as they explore and sample the visual
 scene. Previous studies have demonstrated neural correlates of head and
 eye movements in rodent primary visual cortex (V1), but the sources and
 computational roles of these signals are unclear. We addressed this by
 combining measurement of head and eye movements with high density neural
 recordings in freely moving mice. V1 neurons responded primarily to gaze
 shifts, where head movements are accompanied by saccadic eye movements,
 rather than to head movements where compensatory eye movements stabilize
 gaze. A variety of activity patterns immediately followed gaze shifts,
 including units with positive, biphasic, or negative responses, and
 together these responses formed a temporal sequence following the gaze
 shift. These responses were greatly diminished in the dark for the vast
 majority of units, replaced by a uniform suppression of activity, and were
 similar to those evoked by sequentially flashed stimuli in head-fixed
 conditions, suggesting that gaze shift transients represent the temporal
 response to the rapid onset of new visual input. Notably, neurons
 responded in a sequence that matches their spatial frequency preference,
 from low to high spatial frequency tuning, consistent with coarse-to-fine
 processing of the visual scene following each gaze shift. Recordings in
 foveal V1 of freely gazing head-fixed marmosets revealed a similar
 sequence of temporal response following a saccade, as well as the
 progression of spatial frequency tuning. Together, our results demonstrate
 that active vision in both mice and marmosets consists of a dynamic
 temporal sequence of neural activity associated with visual sampling.
description: Mouse data : Mice were initially implanted
 with a titanium headplate over primary visual cortex to allow for
 head-fixation and attachment of head-mounted experimental hardware. After
 three days of recovery, widefield imaging53 was performed to help target
 the electrophysiology implant to the approximate center of left monocular
 V1. A miniature connector (Mill-Max 853-93-100-10-001000) was secured to
 the headplate to allow repeated, reversible attachment of a camera arm,
 eye/world cameras and IMU21,22. In order to simulate the weight of the
 real electrophysiology drive for habituation, a ‘dummy’ electrophysiology
 drive was glued to the headplate. Animals were handled by the experimenter
 for several days before surgical procedures, and subsequently habituated
 (~45 min total) to the spherical treadmill and freely moving arena with
 hardware tethering attached for several days before
 experiments.  The electrophysiology implant was
 performed once animals moved comfortably in the arena. A craniotomy was
 performed over V1, and a linear silicon probe (64 or 128 channels,
 Diagnostic Biochips P64-3 or P128-6) mounted in a custom 3D-printed drive
 (Yuta Senzai, UCSF) was lowered into the brain using a stereotax to an
 approximate tip depth of 750 µm from the pial surface. The surface of the
 craniotomy was coated in artificial dura (Dow DOWSIL 3-4680) and the drive
 was secured to the headplate using light-curable dental acrylic (Unifast
 LC). A second craniotomy was performed above left frontal cortex, and a
 reference wire was inserted into the brain. The opening was coated with a
 small amount of sterile ophthalmic ointment before the wire was glued in
 place with cyanoacrylate. Animals recovered overnight and experiments
 began the following day. The camera arm was oriented
 approximately 90 deg to the right of the nose and included an eye-facing
 camera (iSecurity101 1000TVL NTSC, 30 fps interlaced), an infrared-LED to
 illuminate the eye (Chanzon, 3 mm diameter, 940 nm wavelength), a
 wide-angle camera oriented toward the mouse’s point of view (BETAFPV C01,
 30 fps interlaced) and an inertial measurement unit acquiring three-axis
 gyroscope and accelerometer signals (Rosco Technologies; acquired 30 kHz,
 downsampled to 300 Hz and interpolated to camera data). Fine gauge wire
 (Cooner, 36 AWG, #CZ1174CLR) connected the IMU to its acquisition box, and
 each of the cameras to a USB video capture device (Pinnacle Dazzle or
 StarTech USB3HDCAP). A top-down camera (FLIR Blackfly USB3, 60 fps)
 recorded the mouse in the arena. The electrophysiology
 headstage (built into the silicon probe package) was connected to an Open
 Ephys acquisition system via an ultra thin cable (Intan #C3216).
 Electrophysiology data were acquired at 30 kHz and bandpass filtered
 between 0.01 Hz and 7.5 kHz. We first used the Open Ephys GUI
 (https://github.com/open-ephys/plugin-GUI) to assess the quality of the
 electrophysiology data, then recordings were performed in Bonsai54 using
 custom workflows (https://github.com/nielllab/FreelyMovingEphys). System
 timestamps were collected for all hardware devices and later used to align
 data streams through interpolation. Marmoset
 data: Electrophysiological recordings were performed
 using 2x32 channel silicon electrode arrays (http://www.neuronexus.com).
 Probes included 2 sharpened tip shanks of 50µm width spaced 200 µm apart,
 each containing 32 channels separated by 35 µm. In one animal we used a
 semi-chronic microdrive (EDDS Microdrive system, https://microprobes.com)
 to place electrodes in cortex for 1-2 weeks over which we made 3-6
 recordings. In the second animal we used a custom micro-drive
 (https://marmolab.bcs.rochester.edu/resources/) to place and remove
 electrodes daily. Arrays were lowered slowly through silastic into cortex
 using a thumb screw. Data were amplified and digitized
 at 30 kHz with Intan headstages (Intan) using the Open Ephys GUI
 (https://github.com/open-ephys/plugin-GUI). The wideband signal was
 high-pass filtered by the headstage at 0.1 Hz, preprocessed by
 common-average referencing across all channels, and then high-pass
 filtered at 300 Hz. The resulting traces were spike sorted using
 Kilosort2. Outputs from the spike sorting algorithms were manually labeled
 using ’phy’ GUI (https://github.com/kwikteam/phy). Any units that were
 either physiologically implausible based on the lack of a waveform with a
 trough followed by a peak or with an inter-spike interval (ISI)
 distribution with more than 1% of the spikes under 1 ms were excluded from
 analyses. Gaze position was monitored using infra-red
 eye tracking methods described previously63. Briefly, the 1st and 4th
 Purkinje images (P1 and P4) were visualized using a collimated IR light
 source and tracked at 593 frames per second to estimate the 2D eye angle.
 The eye tracker was manually calibrated to adjust the offset and gain
 (horizontal and vertical) by showing marmoset monkeys small windowed face
 images at different screen positions to obtain their fixation as described
 previously60,61. Saccadic eye movements were identified automatically
 using a combination of velocity and acceleration thresholds64.

 responsive to saccades. | ## Code/Software All original Python code is
 avaliable on GitHub. Acquisition and preprocessing code:
 [FreelyMovingEphys](https://github.com/nielllab/FreelyMovingEphys).
 Analysis and figure code:
 [freely-moving-saccades](https://github.com/nielllab/freely-moving-saccades). These repositories can be installed and imported as the packages `fmEphys` and `saccadeAnalysis`, respectively (see repositiory READMEs for installation instructions). The hdf files can be read in as: ``` import fmEphys as fme # Read the file in. hffm = fme.read_group_hdf('/.../hffm.h5') # Index into the eye camera timestamps for unit zero. The output will be an array. hffm.iloc[0,'FmLt_eyeT'] ```
