Is short sleep bad for the brain? Brain structure and cognitive function in short sleepers

The paper investigates the effects of short sleep on brain structure and cognitive function, finding that short sleepers without daytime tiredness have larger brain volumes but slightly lower cognitive scores.

Poorer Sleep Health is Associated with Altered Brain Activation During Cognitive Control Processing in Healthy Adults

This study finds that poorer sleep health in healthy adults is linked to altered brain activation during cognitive control tasks, with stronger fronto-parietal and subcortical responses.
