The purpose of this work was to investigate the effects of electrical afterdischarge on protein kinase C (PKC) activity from bag cell neurons (BCNs) of Aplysia. Bilateral clusters of BCNs were divided: one cluster was stimulated to afterdischarge, the other was a control. Clusters were processed for PKC activity assay 5-120 min after electrical stimulation. Afterdischarge triggered a rapid and persistent increase in both calcium-activated and calcium-independent PKC activity.
