Abstract
THE view that the hypothalamus controls the functions of the pars distalis of the pituitary by way of a chemotransmitter transported through the pituitary portal vessels does not accord with the fact that female ferrets, when exposed to added light, will come into heat during the winter months, whether or not there is a direct vascular link between the pituitary and the hypothalamus1. Attention has therefore been turned again to the possibility that peripheral nervous pathways may be concerned in the response.
