Role in "hate Circuit"
Recent, tentative studies have suggested that the putamen may play a role in the so-called "hate circuit" of the brain. A recent study was done in London by the department of cell and developmental biology at University College London. An fMRI was done on patients while they viewed a picture of people they hated and people who were "neutral". During the experiment, a "hate score" was recorded for each picture. The activity in sub-cortical areas of the brain implied that the "hate circuit" involves the putamen and the insula. It has been theorized that the "putamen plays a role in the perception of contempt and disgust, and may be part of the motor system that's mobilized to take action." It was also found that the amount of activity in the hate circuit correlates with the amount of hate a person declares, which could have legal implications concerning malicious crimes.

Famous quotes containing the words role, hate and/or circuit:
“In today’s world parents find themselves at the mercy of a society which imposes pressures and priorities that allow neither time nor place for meaningful activities and relations between children and adults, which downgrade the role of parents and the functions of parenthood, and which prevent the parent from doing things he wants to do as a guide, friend, and companion to his children.”
—Urie Bronfenbrenner (b. 1917)
“Woman learns how to hate to the same extent as she unlearns—how to charm.”
—Friedrich Nietzsche (1844–1900)
“each new victim treads unfalteringly
The never altered circuit of his fate,
Bringing twelve peers as witness
Both to his starry rise and starry fall.”
—Robert Graves (1895–1985)
