Recovery of consummatory feeding behavior after bilateral lesions of the cerebral-buccal connectives in Aplysia californica.
In the sea hare, Aplysia californica, consummatory feeding behavior is selectively abolished by bilateral crushes of the cerebral-buccal connectives and recovers by postlesion day 13. Recovered biting responses are initially weak and increase in magnitude gradually with time. The lesions do not affect appetitive feeding behavior or unrelated reflexive behaviors. Thus, feeding in Aplysia can be used to examine the neural basis of behavioral recovery after CNS injury.
