University College London - Where grey matter sees red

When viewing pictures of someone they hate, people display activity in distinct areas of the brain, new research suggests. Semir Zeki and John Romaya of the Wellcome Laboratory of Neurobiology at University College London examined the brain areas that correlate with the sentiment of hate and found a so-called hate circuit that is distinct from those related to emotions such as fear, threat and danger. The circuit shares a part of the brain that is associated with aggression.
