To sleep deeply: The brainstem neurons that regulate non-REM sleep
Researchers identified neurons that promote non-REM sleep in the brainstem in mice. These neurons commonly expressed the gene that encodes the neuropeptide neurotensin. Activation of these neurons induced non-REM sleep. Moreover, direct administration of neurotensin into the ventricle induced NREM sleep-like brain activity. These findings contribute to our understanding of sleep promotion and sleep disorders, and could tell us more about the evolution of sleep architecture in mammals. Source
Getting too little — or too much — sleep may be bad for the heart
Compared with people who slept for longer or shorter periods of time, those who reported sleeping seven or eight hours a night had significantly less evidence of stiffness in their arteries, indicating a lower chance of developing heart disease or suffering a stroke, according to new research.

Protective brain-cell housekeeping mechanism may also regulate sleep
An important biological mechanism that is thought to protect brain cells from neurodegenerative diseases such as Alzheimer’s and Parkinson’s may also be involved in regulating sleep, according to new research. Source
