Citando:
"A study of 21 people found that for most, feeling down was associated with greater communication between brain areas involved in emotion and memory, a team from the University of California, San Francisco reported Thursday in the journal Cell.
"There was one network that over and over would tell us whether they were feeling happy or sad," says Vikaas Sohal, an associate professor of psychiatry at UCSF.
The finding could lead to a better understanding of mood disorders, and perhaps new ways of treating them."
