ABSTRACT
In the last chapter, we looked at various aspects of the CNS which regulate the systems of defence-safety and go-stop. The CNS co-ordinates attention, appraisal and action in the world. Action is carried out by the body that literally moves the brain around in its environment. Major systems of feedback exist between body and brain. Consequently, any complete picture of psychobiology would fall short of its mark if it did not acknowledge the body as a major source of information and control. The liver, for example, is sometimes called the butler of the brain because amine transport is regulated here. Moreover, the brain must protect the body if it is to survive. Hence, avoiding injury and overload is one of the co-ordinated functions of the brain (mind)-body relation.
