For the first time, a study in mice, to be published in the journal elife, shows that five hours of sleep deprivation leads to a loss of connectivity between neurons in the hippocampus, a region of the brain associated with learning and memory it's clear that sleep plays an important role in memory -- we know that taking naps helps us retain important memories.

Importantly, these risks increase with even mild sleep deprivation of 1-2 hours per night (that’s about 6 hours of sleep) while you are hopefully convinced that sleep is important for many reasons, our focus as learning scientists is on cognition and the ability to learn and remember, so for this blog post i will describe one particular study demonstrating the effect of sleep on learning.
