Study: What Your Brain Is Doing When You Really, Really Hate Someone

Via io9:  ‘[Subjects stared] first at the picture of a person the subjects had neutral feelings toward, and then at the picture of someone they hated. The subjects did this while hooked up to an MRI, allowing the researchers to see which parts of the brain were activated and deactivated…

The parts of the brain activated, the medial frontal gyrus, the right putamen, the medial insula, and the premotor cortex, have come to be known as the “hate circuit.” The premotor cortex is one part of the brain that springs into action when people have feelings of aggression. When we hate, at least part of us is preparing for a physical attack. The frontal gyrus deals with self-awareness, and is involved in go/no go decisions. This part of the brain seems to be in league, however tentatively with the premotor cortex. Haters using the “hate circuit,” then, seem to always be wondering if its the right time to move against the object of their hatred.’
