The ‘hate circuit’ includes structures in the cortex and in the sub-cortex and has components that are important in generating aggressive behaviour, and translating this into action through motor planning, as if the brain becomes mobilised to take some action. It also involves a part of the frontal cortex that has been considered critical in predicting the actions of others, probably an important feature when one is confronted by a hated person.
The subcortical activity involves two distinct structures, the putamen and insula. The former, which has been implicated in the perception of contempt and disgust,
Hate, the polar opposite of love, must have its own discreet circuit. People don’t date, have friendships with, marry or make love to someone that registers on the hate circuit?
“Significantly, the putamen and insula are also both activated by romantic love. This is not surprising. The putamen could also be involved in the preparation of aggressive acts in a romantic context, as in situations when a rival presents a danger. Previous studies have suggested that the insula may be involved in responses to distressing stimuli, and the viewing of both a loved and a hated face may constitute such a distressing signal.
I used to know a couple that started as a professional relationship. Except that she acted as though and told just about everyone that she hated him. Some late night overtime on a project forced them together which also happened to be around a holiday. He didn’t hate her, but knew by way of gossip how she felt. Most of the time if one knows that someone hates them, they at least dislike the hater. In an odd way he didn’t mind it, the hate took some of the sexual tension out of their working relationship. So being the end of the night and the season to be merry and all he offered her a drink. They lived together for almost a year.
In the future we may think twice about leaving our keys lying around, Keys Can be Copied From Afar, Jacobs School Computer Scientists Show
UC San Diego computer scientists have built a software program that can perform key duplication without having the key. Instead, the computer scientists only need a photograph of the key.
There is a photograph at the link of a set of keys made from 195ft away and the working key they made from the photo. They claim that locksmiths have been aware that a good resolution photo could be used to make a copy of a key for some time now. This new software and the ability of computers to extract information previously known only to locksmiths will give amateurs that same ability. They mention that many people at social networking sites will blur out credit card numbers from personal photos, but leave keys in view – que the ominous organ music.
