Brain pattern behind bad mood found
Cell, ● recorded brain activity for a week or more in human volunteers and linked their day- to- day mood swings to specific patterns of brain activity.
The researchers recruited 21 patient volunteers with epilepsy who had had 40 to 70 electrodes implanted on the brain's surface and in deeper structures of the brain as part of standard preparation for surgery to remove seizure- causing brain tissue.
They recorded a wide range of brain activity in these patients over the course of seven to 10 days, focusing on deep brain structures.
Researchers from University of California identified a common pattern of brain activity that may be behind those feelings of low mood, particularly in people who have a tendency towards anxiety
