The emotions are neurochemicals. They wash over us. Cognitive systems have been the focus of brain studies, they are only half the story. Most study of emotion has been behavioural. Only recently has anyone tackled the molecules of matter that are emotions. This must be the reason why some people are addicts. When opiates enter some peoples systems they act as a corrective. They normalise them. The contrasting pictures the cognitive systems and emotional soaking deliver are schizophrenia. Where thoughts and feelings clash. Split brain patients, a treatment for certain extreme forms of epilepsy, have two awarenesses that are seperate. One can be shown a picture of a devil, but the other side will be unable to say what the picture is of. It will be able to say it has a bad vibe though. The emotional reaction comes before recognition. Countless times we have walked in to rooms and felt bad vibes, turned down a street and felt animal fear. We may have not yet been able to figure our what it is we are scared o but we know. These feelings punctuate the lives of some people, wired sensations of distrust. Certainty that things are wrong yet having no way to tell why. This is where the answers to depression, schizophrenia and addiction lie. In the understanding of the biology of mind, the molecules that are our emotions.
