If the exercise was any longer or harder it may have amplified the negative results and became a stressor itself...

​New research has explored how sleep, oxygen levels, and exercise affects our ability to perform mental tasks.

Depression can have an impact on the physical health of your brain, research shows. Here’s how.

Northwestern University scientists may have figured out why pulling an all-nighter can leave us feeling loopy and downright giddy for days after. In a new study out this week, the researchers found that acute sleep deprivation in mice can trigger a rapid release of dopamine within the brain and boost its plasticity, temporarily creating hyperactive and antidepressant effects. The findings might actually help scientists learn how to craft better treatments for mood disorders, the authors say.

Deep learning and predictive coding architectures commonly assume that inference in neural networks is hierarchical. However, largely neglected in deep learning and predictive coding architectures is the neurobiological evidence that all hierarchical cortical areas, higher or lower, project to and receive signals directly from subcortical areas. Given these neuroanatomical facts, today’s dominance of cortico-centric, hierarchical architectures in deep learning and predictive coding networks is highly questionable; such architectures are likely to be missing essential computation...
