Behavioral Choice: Neural Mechanisms in Pleurobranchaea
Science, 1977In the marine mollusk Pleurobranchaea , it is known that feeding occurs and withdrawal from tactile stimuli is suppressed when the sensory stimuli for feeding and withdrawal are presented simultaneously. This "dominance" of feeding behavior over withdrawal behavior occurs because the central nervous network ...

Learning: Classical and Avoidance Conditioning in the Mollusk Pleurobranchaea
Science, 1973Naive specimens of the marine gastropod Pleurobranchaea withdraw from tactile stimulation of the oral veil and show feeding responses to food chemicals. Experimental subjects, trained by pairing touch (conditioned stimulus) with food chemicals (unconditioned stimulus), soon acquired a classically conditioned feeding

Discriminative behavior and pavlovian conditioning in the mollusc Pleurobranchaea
Journal of Neurobiology, 1986AbstractThe buccal motor system in the sea slug Pleurobranchaea californica is multifunctional; similar sets of neurons and muscles generate different behaviors through similar electrophysiological motor patterns. Such multifunctional systems compromise the traditional practice of identifying a motor pattern and then using that pattern to indicate the ...

Pleurobranchaea behavior: Food finding and other aspects of feeding
Behavioral Biology, 1974Investigations of Pleurobranchaea californica, a marine gastropod mollusk, have demonstrated its potential for the study of neural mechanisms underlying behavior. In this paper, we have examined certain behaviors which lay a foundation for such studies.

Behavioral state changes induced in Pleurobranchaea and Aplysia by serotonin
Behavioral and Neural Biology, 1982The effects of serotonin injection on behavioral states and feeding in Pleurobranchaea californica and behavioral states and spontaneous behaviors in Aplysia californica were examined. Serotonin (10−7 moles/kg body wt) increased behavioral state level in both species from still states to alert and moving states.

Learning: Rapid Aversive Conditioning in the Gastropod Mollusk Pleurobranchaea
Science, 1975Untrained Pleurobranchaea feed voraciously when presented food and withdraw from electrical shocks. We trained experimental animals in ten trials spaced 1 hour apart to withdraw from food alone by electrically shocking them if they fed or were indifferent to food.

Hyperphagia resulting from gut denervation in the sea slug, Pleurobranchaea
Behavioral and Neural Biology, 1987Previous research suggests that gut distension by ingested bulk plays an important role in the regulation of food intake in gastropod molluscs. The present study tested whether the bilateral stomatogastric nerves which innervate the esophagus and crop in Pleurobranchaea form a neural pathway carrying information about gut distension to the central ...

Neural Correlate of Behavioral Plasticity in Command Neurons of Pleurobranchaea
Science, 1978Food stimuli normally excite the command neurons of Pleurobranchaea that cause feeding. In contrast, the same food stimuli selectively inhibit these neurons in specimens that have been trained to suppress feeding and withdraw from food by means of an avoidance conditioning paradigm consisting of paired food and ...

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2009
Glycine (Gly) is one of the amino acids that most strongly provoke feeding behavior in the carnivorous opisthobranch sea slug Pleurobranchaea japonica. Placing of an aliquot of a Gly solution in front of the anterior end of this animal induced feeding responses such as orientation to the origin of the stimulus and extrusion of the proboscis.

1. The paracerebral neurons (PCNs) in the brain of the mollusk Pleurobranchaea are a population of 12-16 interneurons that send axons to the buccal ganglion and control cyclic feeding behavior (9). In the present study we show that the PCNs differ in size and that a number of functional and structural properties of the PCNs are closely correlated with
