A recent American study indicates that when we face social rejection, the brain has a means to alleviate the pain it causes us. According to scientists at the University of Michigan School of Medicine published in Molecular Psychiatry, the brain's system of natural painkillers not only responds to physical pain in the body, as has already been shown, but also to social rejection.

Researchers at the University of Rochester (USA) have carried out a study that demonstrates the restorative nature of sleep and that could explain why we need to sleep, according to the journal Science in its latest edition.

Researchers in behavioral neuroscience at Connecticut College, in the United States, have shown that the famous Oreo cookies are as addictive as cocaine, at least for laboratory rats. And curiously, like humans, these rodents usually open the cookie and eat the cream that it contains in the center first.

Although we usually associate the feeling of having a word "right on the tip of the tongue", and not finding the appropriate term for something that is well known to us, as a sign that something in our memory is failing, they have just shown that it does not save relationship.

People who sleep more than 9 hours a day experience a cognitive decline much faster than those who only iron the hour for a period of 6 to 8 hours a day, according to a study just published in the journal 'Journal of Psychiatric Research '.

Chiari malformation is a congenital disease linked to the X chromosome. It occurs when the cerebellum, the organ in charge of controlling balance and neuromuscular coordination, descends through the major orifice of the skull and compresses the brain stem causing a brain herniation. In some cases, this structural defect leads to an excessive accumulation of brain fluid (hydrocephalus) that can cause serious mental damage.

There are some similarities between the brain and computers, but the most interesting are all the differences that make our thinking organ really spectacular. Enrique Noé, Research Director of the Brain Injury and Neurorehabilitation Service at NISA Hospitals explains what is special about the brain and how we can compare it with current computers.
