How does the brain function during sleep?

How (does) the brain function during sleep?

I think it’s pretty logical for everybody that our brain doesn’t simply shut down during sleep. Had it not had to regulate the vegetative processes, maybe it should have shut down, but since it really has to control the heart rate, the digestive system and all the other (non-autonomic and vegetative) functions, it has to […]

Although there are rare the cases in which the small brain needs to be surgically removed, it’s generally accepted by the medical society that the body can live without it, not without some sort of consequences. The small […]

Is a small structure that, despite of its small size, links the nervous system to the endocrine system, asides from many other roles that it has. In terms of size, this organ is no […]

Perhaps the most interesting characteristic is that, despite its size (about 9 times bigger than the cerebellum), it has an equal amount of neuronal cells. Basically, the cerebrum is physically divided in two hemispheres (the cerebral cortex), but comprises as well the […]
