Central Correlates of Taste-Discrimination in the Terrestrial Slug Limax Maximus
Using an in vitro preparation consisting of lips, cerebral ganglia (CG) and buccal ganglia (BG) we have identified a group of cerebral to buccal interneurons (CB,s) which have powerful initiating and modulating effects on fictive feeding rhythm (Delaney and Gelperin, 1986; Gelperin, 1986; King et al., 1987). CB's receive synaptic input from lips mechanoreceptors and chemoreceptors, feedback from the BG during fictive feeding and strong inhibitory input from stimuli which elicit withdrawal in the whole animal such as electric shock of the foot.
