Sleep Deprivation may Lead to Impaired Memory, Says Study
Researchers from the Princeton University have stressed the importance of adequate sleep, the lack of it could lead to impaired memory. This was found when researchers studied rats that were deprived of sleep for 72 hours.

Elizabeth Gould, lead researcher, said: "The decrease in neuron production coincided with an increase in the major rodent stress hormone, corticosterone. We know that sleep deprivation is stressful, and that it impairs certain types of learning and memory. We concluded that sleep deprivation decreases neurogenesis by elevating stress hormones."

The findings of this research are published in the latest issue of New Scientist.
