Feeding in Helisoma trivolvis: The Morphological and Physiological Bases of a Fixed Action Pattern

Feeding in Helisoma trivolvis: The Morphological and Physiological Bases of a Fixed Action Pattern Abstract This report is a description of feeding in the pulmonate snail, Helisoma trivolvis and provides a detailed account of: (i) the behavior, (ii) the muscular system, (iii) the muscle activity patterns, (iv) the neuromusculai relationships, (v) the motoneurons to specific muscles, and finally, (vi) an introduction to the premotor system. Feeding is the result of the integration of sensory information onto components of a central program which is delived from connections within the buccal ganglia. This report emphasizes the analysis of the centrally programmed components of the feeding output by characterizing interactions among three classes of neurons (approximately 50 cells) in the buccal ganglia: protractor motoneurons, retractor motoneurons, and the neurons of an electrically coupled neural network which produces both the timing and driving of motoneuron activity.

Abstract

Abstract This report is a description of feeding in the pulmonate snail, Helisoma trivolvis and provides a detailed account of: (i) the behavior, (ii) the muscular system, (iii) the muscle activity patterns, (iv) the neuromusculai relationships, (v) the motoneurons to specific muscles, and finally, (vi) an introduction to the premotor system. Feeding is the result of the integration of sensory information onto components of a central program which is delived from connections within the buccal ganglia. This report emphasizes the analysis of the centrally programmed components of the feeding output by characterizing interactions among three classes of neurons (approximately 50 cells) in the buccal ganglia: protractor motoneurons, retractor motoneurons, and the neurons of an electrically coupled neural network which produces both the timing and driving of motoneuron activity.
