What Is Depression Dulls Brain

[treasurebox]

Depression is well known for dulling people's sense of pleasure, and now, researchers have used high-tech brain scans to watch that happen inside the depressed brain.Their findings -- which appear in the advance online edition of NeuroReport -- show that when depressed people listened to music they liked, the brain's reward-processing areas weren't as active as when people who weren't depressed listened to their favorite music.

The study included 15 healthy young adults and 16 young adults who had been diagnosed with major depression. Only one of the depressed participants was taking an antidepressant.
