SHY Hypothesis Explains That Sleep Is the Price We Pay for Learning

RATE THIS! +8
Posted in Science on 13th Jan, 2014 10:52 PM by AlexMuller

Why do animals ranging from fruit flies to humans all need to sleep? After all, sleep disconnects them from their environment, puts them at risk and keeps them from seeking food or mates for large parts of the day.

 
Two leading sleep scientists from the University of Wisconsin School of Medicine and Public Health say that their synaptic homeostasis hypothesis of sleep or "SHY" challenges the theory that sleep strengthens brain connections.
 
The SHY hypothesis, which takes into account years of evidence from human and animal studies, says that sleep is important because it weakens the connections among brain cells to save energy, avoid cellular stress, and maintain the ability of neurons to respond selectively to stimuli.
 
"Sleep is the price the brain must pay for learning and memory," says Dr. Giulio Tononi, of the UW Center for Sleep and Consciousness. "During wake, learning strengthens the synaptic connections throughout the brain, increasing the need for energy and saturating the brain with new information. Sleep allows the brain to reset, helping integrate, newly learned material with consolidated memories, so the brain can begin anew the next day. "
 
Tononi and his co-author Dr. Chiara Cirelli, both professors of psychiatry, explain their hypothesis in a review article in today's issue of the journal Neuron. Their laboratory studies sleep and consciousness in animals ranging from fruit flies to humans; SHY takes into account evidence from molecular, electrophysiological and behavioral studies, as well as from computer simulations. "Synaptic homeostasis" refers to the brain's ability to maintain a balance in the strength of connections within its nerve cells.

We all recognise that no animal can go without sleep, just like food and water. Now this hypothesis provides a good framework to establish what are critical changes that happen during the sleep - link to learning and memory highlights how critical sleep is Reply

This is an important study. SHY takes into account evidence from molecular, electrophysiological and behavioral studies, as well as from computer simulations. Reply

It would be great to find out about the possibly that sleep has a crucial role during development, a time of intense learning and massive remodeling of brain. Reply

Hi there! I know this is kinda off topic however I’d figured I’d ask. Would you be interested in trading links or maybe guest writing a blog post or viceev-rsa? My website goes over a lot of the same subjects as yours and I believe we could greatly benefit from each other. If you happen to be interested feel free to send me an e-mail. I look forward to hearing from you! Wonderful blog by the way! Reply
