Instincts not only generate feelings but also command appropriate action that satisfy the need. Animals just act out instinctive rituals of eating, courtship and fighting, because they do not possess a reasoning mind. Man, on the other hand, because he has the reasoning mind, can control his responses to the insistence of the instinctive drives. Of course, man also does feel angry, hungry or sexually aroused. But he can modify his action. He could, for example, channel an erotic mood on to another creative track or refuse fatty food after a look at his bulging waist line.
So far, we had believed that the brain was the source of energy and the place from which the will acted; but now, we know that it is only the repository of memories. The neuro-endocrine system is the seat of the impulses of man. For instance, love, hate and fear are endocrine impulses. It is the primitive urge of aggression from the endocrines that will start war and not the brain, because no reasoning mind will ever wish to kill. It can stabilize love but the impulse does not come from conscious thinking. All the emotions and impelling forces are the actions of the endocrine expression.
As research deepens our knowledge of co-ordinatory systems-neuro-endocrine systems-it becomes increasingly apparent that hormones and neurohormones participate in every bodily function and have profound influence upon the mental states and tendencies, behavioural patterns as well as emotions of an individual.
The complex of endocrine system includes the pineal, the pituitary, thyroids, para-thyroids, thymus, adrenals, gonads, pancreatic islets and the hormone-producing part of the gastro-intestinal tract. All these glands are comparatively small, are ductless and have access to rich visceral supply. The entire system, aptly called endocrine orchestra, works in harmony. The known methods of inter-communication are electrical impulses of the nerve action and the chemical messengers.
