The number of friends we have on the social network Facebook is linked to the size of certain brain regions. This is deduced from a study carried out by scientists from the Institute of Cognitive Neurosciences at University College London (United Kingdom), who scanned the brains of 125 university students who were Facebook users and compared the results with the size of their groups of friends, both in the social network as in the real world.
The signals that are generated in the brain when a person succeeds or fails are not processed in a restricted area of the cerebral cortex. The neural connections in these cases extend practically throughout the brain, according to a study by Yale University 'that appears published in the latest edition of the journal' Neuron '.
A Yale University study published in the journal Neuroscience reveals that when the creation of new neurons is disrupted in adolescence, individuals become deeply antisocial. However, if the same process is interrupted in adults, no behavioral changes are observed.
Face recognition is a fundamental tool for social interactions between human beings. Without the ability to read other faces and their expressions, it would be difficult to tell friends from strangers at first glance, and we couldn't tell a sad person from a happy one.
In the nose there are 400 different types of olfactory receptors that are organized according to a scale that places the most pleasant at one extreme and the most foul at the opposite pole. This is the conclusion reached by researchers from the Weizmann Institute (USA) in a study published today in the journal Nature Neuroscience.
David M. Eagleman, a neuroscientist at the Baylor School of Medicine, has specialized in studying the phenomena related to the perception of time by the human brain. And after several studies with functional magnetic resonance imaging, he has come to the conclusion that when an experience is new or surprising, the activation of our neurons to register it increases.
Scientists from the Hotchkiss Brain Institute (HBI), University of Calgary (Canada), have discovered a mechanism by which stress increases food gathering in rats. The finding, published this week in "Neuron," provides important clues to why stress could be one of the biggest contributors to obesity.
Our brain, quite adept at knowing the position of our body on land, is not as efficient when calculating the position at a certain height. A team of British scientists from University College London has shown that the internal spatial map of the brain is flat, and that when we fly a plane or go into outer space it works badly.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
