In a recent study, neuroscientists at UC Berkley found an interconnected link between slow brain waves generated during sleep and the consolidation of memories in the hippocampus region of the brain. This brain area it seems provides short term memory storage and processing before being delivered to the prefrontal cortex’s longer term memory “hardrive”.
In a research paper published in the online journal Neurology, scientists have discovered a potential link between poor REM sleep in both Dementia and Parkinson’s diseases.
ScienceDaily (July 17, 2012) — Two powerful brain chemical systems work together to paralyze skeletal muscles during rapid eye movement (REM) sleep, according to new research in the July 18 issue of The Journal of Neuroscience. The finding may help scientists better understand and treat sleep disorders, including narcolepsy, tooth grinding, and REM sleep behavior disorder.
According to a 2011 study entitled: Functional Neuroimaging Insights into the Physiology of Human Sleep. by researchers Thien Thanh Dang-Vu, MD, PhD, Manuel Schabus, PhD and others, it shows that when “sleep spindle” shaped brainwaves are present, the auditory sound input is blocked out. So for all intents and purposes you can snooze right next to your human buzz-saw of a partner and never hear a peep.
