[The effect of picrotoxin-induced seizure activity on the cAMP-dependent phosphorylation of synapsin-I in rats].

Picrotoxin administration decreased the incorporation of labelled phosphate in neurospecific protein synapsin I in vitro in cortex. In the animal hippocampus, the incorporation was more expressed. The data obtained suggest that activation of the cAMP-dependent phosphorylation occurs during seizure in the cortex.
