Steroid Sensitivity of the Nervous System
The nervous system of both vertebrates and invertebrates possesses groups of cells which release hormones. During the past decade, considerable attention has been paid to the output mechanisms of these so-called neuroendocrine cells. Much less is known about the input. In a previous paper (Schadé and van Wilgen-burg 1970) we showed that neuroendocrine cells of a snail (Helix pomatia) responded to circulating steroids by either a decrease or an increase of the membrane potential and thus altered the firing rate.
