Discover how sadness is "seen" in the brain

Scientists have found that it is associated with the connection between memory and emotions

United States.- US scientists from the University of California at San Francisco (UCSF) have looked at how sadness is in the human brain, according to a study published in Cell magazine on Thursday.

The researchers included 21 respondents and concluded that for most of them, the sense of sadness was associated with greater communication between brain parts involved in emotion and memory.

It has been previously investigated that sorrow and other emotions include amygdala, almond-shaped mass on each side of the brain, and there is evidence that the hippocampus, which is associated with memory, can play some role. in emotions. Scientists from the University of California, in turn, studied exactly what is happening in the brain when a person's mood changes.

The 21 people involved in the study were in a hospital waiting for brain surgery because of severe epilepsy. Before surgery, doctors inserted small wires into the brain and controlled their electrical activities for a week, which helped scientists to see whether certain moods matched with communication within certain brain networks.

Pressure comfort

As a result, scientists have found that 13 out of 21 patients share the same network in the brain, ie in the brain of these people, the authors have noticed the connection between grief and a certain neuronal circuit that links the emotional fluctuation amygdal with the hippocampus, which helps in storing memory.

"There was a network that told us again and again whether they felt happy or sad," said Associate Professor of Psychiatry at UCSF and one of the authors of the Vikaas Sohal study quoted by NPR.

In addition, the study provides a detailed map of what is happening in the human brain, which is what doctors and scientists need to look for better treatments for patients with mood disorders. In addition, finding can provide comfort to people with depression.

"As a psychiatrist, it's incredibly powerful to tell patients:" Hey, I know something's happening in the brain when you feel depressed, "Sohal said.
