Sex-specific differences in hippocampal gene regulation following acute sleep deprivation

Lisa Lyons, Natalie Storch, Yann Vanrobaeys et al. · FENS Forum 2024

…significant impairments in memory and performance. The hippocampus is particularly susceptible to the effects of sleep deprivation. Increasingly, studies suggest sex-specific behavioral differences occur following acute sleep deprivation, but almost all molecular studies have examined changes in males. Consequently, we investigated changes in gene expression following acute sleep deprivation in female mice at different estrous stages. Following one week of individual housing and pre-han

This presentation delves into the necessity for simplified models in the field of psychological sciences to cater to a diverse audience of practitioners. We introduce the #PsychMapping model, evaluate its merits and limitations, and discuss its place in contemporary scientific culture. The #PsychMapping model is the product of an extensive literature review, initially within the realm of sport and exercise psychology and subsequently encompassing a broader spectrum of psychological sciences. This model synthesizes the progress made in psychological sciences by categorizing variables into a fra

Movements and engagement during decision-making

Anne Churchland · University of California Los Angeles, USA

When experts are immersed in a task, a natural assumption is that their brains prioritize task-related activity. Accordingly, most efforts to understand neural activity during well-learned tasks focus on cognitive computations and task-related movements. Surprisingly, we observed that during decision-making, the cortex-wide activity of multiple cell types is dominated by movements, especially “uninstructed movements”, that are spontaneously expressed. These observations argue that animals execute expert decisions while performing richly varied, uninstructed movements that profoundly shape neu

Trading Off Performance and Energy in Spiking Networks

Sander Keemink · Donders Institute for Brain, Cognition and Behaviour

Many engineered and biological systems must trade off performance and energy use, and the brain is no exception. While there are theories on how activity levels are controlled in biological networks through feedback control (homeostasis), it is not clear what the effects on population coding are, and therefore how performance and energy can be traded off. In this talk we will consider this tradeoff in auto-encoding networks, in which there is a clear definition of performance (the coding loss). We first show how SNNs follow a characteristic trade-off curve between activity levels and coding lo
