A group of American researchers from the University of California in San Francisco (UCSF) have looked at how sadness looks in human brain, according to a study published in the Cell newspaper on Thursday.

The researchers involved 21 people in the study and found that for most of them the feeling of sadness was associated with increased communication between the brain's areas that touched emotions and memory.

Previously, it has been investigated that sadness and other feelings include amygdala, an almond mass found on each side of the brain, and there is evidence that the memory of hippocampus can play a part. in emotions. Researchers at the University of California, in turn, studied exactly what happens in the brain when a person's mood changes.

The 21 people who participated in the study were in a hospital waiting for brain surgery for severe epilepsy. Prior to surgery, doctors introduced small threads into the brain and checked their electrical activity for a week, which helped researchers see if some mood coincided with communication within specific brain networks.

Comfort for the depressed

As a result, the researchers discovered that 13 of 21 patients shared the same network in the brain, ie in the minds of these individuals, the authors observed a link between grief and a particular neuronal circuit that connects the amygdala that deals with emotional fluctuations, with hippocampus, which helps to store memories.

"There was a network that told me over and over if they felt happy or sad," says Professor of Psychiatry at UCSF and one of the study's writers, Vikaas Sohal, quoted by NPR.

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

"As a psychiatrist, it's incredibly powerful to say to patients," Hi, I know something happens in your brain when you feel depressed, "stressed Sohal.
