Sleep linked to brain cell creation - neurogenesis

BrainConnection - The Brain and Learning: (UPI via COMTEX)
" Losing sleep may cause the brain to stop producing new brain cells, a study conducted by New Jersey's Princeton University has found...By depriving rats of sleep for 72 hours, the researchers found that those animals consequently had increased amounts of the stress hormone corticosterone, and produced significantly fewer new brain cells in the hippocampus...When the rats' sleep patterns were returned to normal a week later, their levels of nerve-cell production remained hindered for two weeks."
