1. The pteropod mollusk Clione limacina is a predator, feeding on the small pteropod mollusk Limacina helicina. Injection of gamma-aminobutyric acid (GABA) into the hemocoel of the intact Clione evoked some essential elements of the hunting and feeding behavior, i.e., protracting the tentacles, opening the mouth, and triggering the rhythmic movements of the(More)
1. We have identified and characterized a family of several pairs of neurons in the cerebral ganglion of Aplysia brasiliana that are capable of inducing, maintaining, or modulating a motor program that underlies swim locomotion in this marine mollusk. We have operationally defined these cells as command neurons (CNs) for swimming. 2. The command cells occur(More)
The effects of gamma-aminobutyric acid (GABA) on the behaviour of the marine pteropod mollusc Clione limacina were studied. In intact molluscs, injection of GABA evoked the consummatory stage of feeding behaviour, i.e. protracting the tentacles, opening the mouth, catching and swallowing prey, as well as some acceleration of locomotion. In the isolated CNS,(More)
1. A contact of the pteropod mollusk Clione limacina with its prey (small pteropod mollusk Limacina helicina) evokes a complex pattern of hunting and feeding behavior: protraction of tentacles to seize the prey, activation of buccal apparatus to swallow the prey, activation of locomotor system (speeding up of wing beating), reversal of reaction to tactile(More)
