How Does Sleep Affect the Brain

New research according to Drs. Chiara Cirelli and Giulio Tononi, found that during sleep your brain shrinks.  More specifically, the brain’s synapses (the connections among neurons) shrink by nearly 20 percent during sleep.  This time allows the synapses to rest and get ready for the deluge of information they will have to process the next day.

“During sleep, we are much less preoccupied by the external world…and the brain can sample all our synapses, and renormalize them in a smart way.” Cirelli to Live Science.

Cirelli and Tononi introduced their research on this subject in 2003, but now have direct visual evidence after observing the shrinking of synapses in mice while they sleep.  Sleep is important for refreshing the brain, giving it the ability for storing memories and for learning. Synapses are constantly strengthening or widening to accommodate for the flow of information your brain is receiving during your waking hours.  After so long, the brain gets overloaded with information and needs rest to rejuvenate.  During sleep the synapses do a sort of pruning in order to remove the information that is not needed and store the most important information as memory.  Therefore, the brain then doesn’t get overloaded with inessential information.
