Abstract

The serotonergic metacerebral cells (MCCs) of Aplysia were destroyed by intracellular injection of proteolytic enzyme. MCC-lesioned animals showed alterations of biting responses compared to MCC-sham and B-cell-lesioned control animals, as well as to their own preoperative behavior. The alterations of biting responses included a prolongation of the duration of radula protraction and a lengthening of interbite interval. No changes were observed in non-biting feeding responses and in behaviors unrelated to feeding.
