Identified neuronal individuals in the buccal ganglia of Helix pomatia

Abstract

The buccal ganglia of Helix pomatia are used as model nervous structures in neurophysiological and in epileptological studies. Many basic problems concerning membrane physics, functioning of the single neurons and of neuronal networks can be studied easily using these ganglia. The model character mainly comes from the relative simplicity of this nervous system and that it contains large visually identifiable neurons. As in other invertebrate nervous systems, the large neurons have proved to be individuals showing the same functional and structural properties from one animal to the next.
