title: <b>Initial phenotypic heterogeneity determines the stability of syntrophic bacterial consortia</b>

description: Bacteria frequently engage in syntrophic interactions with other microorganisms through metabolite exchange, yet the mechanisms sustaining their stability remain poorly understood. Here, we combine evolutionary experiments and validation assays to investigate how phenotypic heterogeneity in amino acid production stabilizes syntrophic interactions between <i>Escherichia coli</i> lysine- (ΔL) and arginine-auxotroph (ΔA). In a 27-day evolution experiment, growth ceased in 70% of cocultures, with mutual benefit transitioning to amensalism as both auxotrophs reduced partner-essential amino acid production. However, 30% of cocultures maintained stable mutual beneficial relationships and ancestral fitness levels, with amino acid production levels unchanged. Subsequent validation experiments revealed that pre-existing phenotypic heterogeneity - variability in amino acid production among genetically identical strains - determined consortium outcomes. Cocultures pairing initial low-production ΔL and ΔA strains exhibited greater stability than high-production consortia. We showed that higher amino acid production was rather unfavorable to consortium fitness. High amino acid production strains incurred fitness trade-offs to elevated mortality and metabolic redundancy, resulting in the destabilizing of mutually beneficial interactions. Our findings demonstrate that pre-existing phenotypic heterogeneity in initial levels of amino acid production determines variation in the outcomes of inter-strain interactions, offering insights into the stability of microbial communities.

title: An open dataset for cognitive training effects on brain and cognition in older adults with subjective memory decline
title: 认知训练对主观记忆下降老年人大脑及认知功能的影响

description: Neuroimaging findings suggest that older adults with subjective memory decline (SMD) demonstrate some neurodegenerative brain changes and have high risk of developing dementia, but relatively little is known about the effectiveness of interventions for SMD. This study aimed to examine the effects of cognitive training on resting-state brain activity in SMD.The image data was obtained using a 3-Tesla Siemens Trio scanner. After MRIQC screening and withdrawal of some subjects, the final resting-state functional connectivity analysis included a total of 15 subjects in the control group (M=71.53 ± 6.15 years old; 6 males), training group of 20 (M=74.10 ± 3.48 years old; 6 males).

title: An Open Dataset for Multimodal Intervention in Older Adults

description: The prefrontal cortex and medial temporal lobe are particularly vulnerable to the effects of aging. The disconnection between them is suggested to be an important cause of cognitive decline in normal aging. In the present study, using a multimodal intervention comprised of cognitive training, Tai Chi and group counselling, we charted activity-driven, whole-brain functional-connectivity plasticity in healthy older adults. Specifically, we conducted a 6-week intervention trial with 45 community-dwelling older adults assigned to one of the 2 groups (multimodal intervention or control), 34 participants were included in the final analyses: 17 in the intervention group (9 men,mean age: 68.6 ± 5.7 years) and 17 in the control group (11 men, mean age: 71.7 ± 4.0 years).The image data was collected using a 3.0-Tesla Siemens Trio scanner (Erlangen, Germany) located at the Beijing MRI Center for Brain Research.

title: An Open Dataset for Combined Aerobic Exercise and Video Game Intervention in Older Adults

description: Mnemonic discrimination is very vulnerable to aging. Previous studies have reported that aerobic exercise and enriched cognitive stimulation (e.g., video games) could improve mnemonic discrimination in older adults. The animal model suggested that combining the 2 training methods could result in a larger improvement. However, there is limited evidence on the potential superior efficacy of combined intervention with human participants. Moreover, the neural basis of this potential superior is poorly understood.In the present dataset, we conducted a 16-week intervention trial with 98 community-dwelling older adults assigned to one of the four groups (combined training, aerobic cycling alone, video game alone, or passive control). The image data was obtained using a 3 Tesla GE Discovery MR750 Magnetic Resonance Scanner with 8-channel head-coils.

title: Time Pressure Modulates the Effects of Reward and Punishment on Working Memory for Non-Semantic Characters: Evidence from fMRI
title: 时间压力下奖惩对工作记忆的影响

description: Anticipation of reward and punishment modulates working memory performance by influencing motivational states and attentional resource allocation, thereby affecting encoding, maintenance, and retrieval processes. Although prior studies have demonstrated that reward- and punishment-related cues enhance task engagement, it remains unclear whether such motivational effects vary as a function of time pressure and how they are instantiated at the neural level. To address these questions, the present study employed an encoding–test working memory task with non-semantic characters as stimuli, manipulated time pressure and reward/punishment conditions, and combined behavioral measures with functional magnetic resonance imaging (fMRI) to examine the neural mechanisms underlying the effects of time pressure and reward/punishment anticipation on working memory.

After excluding items with emotion type recognition accuracy&lt;90%, 30 items were selected as formal materials under both positive and negative conditions. Perform one-way ANOVA on the efficacy and arousal of positive and negative barrage using SPSS to ensure that there is no significant difference in efficacy and arousal between the two types of barrage.
