Hate involves both the interior, primitive parts of the brain? Our capacity for intense dislike of others of our species may date back as far as 150,000 years. When subjects saw someone they hated, most of the frontal cortex remained active. The more intensively a person said that he or she hated another person, the more energetically the subject’s frontal cortex lit up at the sight of the person.
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 it’s the right time to move against the object of their hatred.
The putamen also lights up when a person is planning aggressive acts.
When we love someone, we shut off the part of our brain that judges – a trait that, we hope, has led to more happiness than sorrow. When we hate someone, we leave the judgment part of our brain a’blazing.
