Decreased resting membrane conductance as the proximate cause of burst modulation by an identified interneuron in Helix.
The mechanism by which an identified interneuron modulates bursting activity was studied in the mollusc Helix pomatia. Firing of the interneuron was found to enhance endogenous bursting activity by causing a slow, persistent decrease in resting K-conductance, leading to a relative increase in the effectiveness of the burst-generating mechanism.
