Neurophysiology of feeding

In inrestigations o f the neural processes und¢rlytng tarious behavioural phenomena, it is often rerj di~icult to separate cause from effect, especially when the part of the nervous system central to this control is distant from both ¢h ~. sensory and the motor ends of :his behariour. Orercoming fheye di~eu_t~fas. Edmund Roi:~, with his colleagues, has carried out a series of rery elegant experiments which have succeeded in dissecting ap~,t the various types of neurones inroh'ed in feeding behaviour, and. in doing so, has provL'ied intriguing information as to the separate roles of these differen" neurones.
