Sleep Deprivation May Impair Memory

Staying Up All Night Makes for Fuzzy Memories, Study Shows WebMD 2/12/07 "Sleep deprivation tends to hamper the brain's ability to make new memories, a new study shows. The study, published online in Nature Neuroscience, comes from researchers at Harvard Medical School and Boston's Beth Israel Deaconess Medical Center"

The researchers found that just one night of sleep deprivation has significant effects on memory. The theory is that either sleep deprivation itself prevents new memory formation, or that the brain is overwhelmed and cannot properly lay down the memory for later recall. Specific details are lacking in the articles on this so far.

Maybe associated with this is another study from Princeton that shows that sleep deprivation prevents new cell formation in the hippocampus.
