Lack Of sleep Can Impair Memory

Older people who don’t sleep well have more problems remembering things because it prevents memories from being stored at night.

Researchers found that memories in the brains of old people rarely get into the ‘hard drive’ or prefrontal cortex, instead staying in the hippocampus. Using functional and structural Magnetic  Resonance Imaging  (MRI) scans, researchers found that healthy adults spend about a quarter of their sleep in deep and restorative sleep called non-rapid –eye-movement sleep, during which the brain’s middle frontal lobe generates slow waves.
