More about the insula, a small but key part of the human brain

WEDNESDAY, Oct. 29 (HealthDay News) — British researchers say they’ve identified a “hate circuit” in the brain.

This hate circuit shares part of the brain associated with aggression, but is distinct from areas related to emotions such as fear, threat, and danger, said researchers Professor Semir Zeki and John Romaya, of University College London’s laboratory of neurobiology.

The study was published online Oct. 29 in the journalPLoS One.

“Hate is often considered to be an evil passion that should, in a better world, be tamed, controlled, and eradicated,” Zeki said in a journal news release. “Yet to the biologist, hate is a passion that is of equal interest to love. Like love, it is often seemingly irrational and can lead individuals to heroic and evil deeds. How can two opposite sentiments lead to the same behavior?”
