Studies of the Rf = 0.58 protein in common snail command neurons during learning.

Levels of the acidic brain-specific Rf = 0.58 protein in neurons of the subglottal complex of ganglia were studied in the common snail during the process of acquisition of defensive food aversion. Levels were significantly increased in neurons LPa3 and RPa3 at both the early and late stages of learning. There was a tendency to increased protein levels in neurons LP11 and RP12, while there were no changes in levels in neuron RPa5 and pool D. The level of involvement of defensive behavior command neurons appears to be determined by the specific involvement of their receptor and effector fields.
