Sleep News and Research

RSS

Sleep is a physiological behavior that is common in all animal species. It forms around one third of a human life. It is not known clearly the exact functions of sleep but it seems to be essential for survival as prolonged sleep deprivation leads to severe physical impairment followed by cognitive loss and eventually death.

Seasonal Light Changes Continue to Shape Human Circadian Rhythms

It’s tempting to think that, with our fancy electric lights and indoor bedrooms, humanity has evolved beyond the natural influence of sunlight when it comes to our sleep routines.

New Discovery Sheds Light on How Monoamines Regulate Brain Rhythms

A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.
