"Several studies have shown that sleep contributes to brain plasticity in general , and to adult neurogenesis, in particular," said Dr. McGinty. "Neurogenesis is a concrete example of brain plasticity, suppression of adult neurogenesis is thought to be important in pathologies such as depression. One current question has to do with the relative contribution of the two sleep states, non-REM and REM, which have very different, even opposite, physiological properties. This study showed that REM sleep has a critical role in facilitating brain plasticity. The study does not exclude an equally important role for non-REM sleep. In other recent work, we have shown that sleep fragmentation can also suppress adult neurogenesis. How sleep affects the molecular mechanisms underlying neurogenesis remains to be explored."

It is recommended that older adults get between seven and eight hours of nightly sleep.
