1. 1. EEG activity was assessed in rats following the intraventricular injection of cholinergic agonists (carbamylcholine and nicotine tartrate), nicotinic antagonists (d-tubocurarine and α-bungarotoxin), ganglionic blockers (mecamylamine and hexamethonium), decamethonium, antibodies prepared against purified electric fish acetylcholine receptor, and human sera from myasthenic and epileptic patients. 2. 2. Seizures were produced only by agonists and nicotinic antagonists. 3. 3. Carbamylcholine produced clonic/tonic convulsions. Nicotine resulted in a depressed EEG with sporadic seizures. 4. 4. Both antagonists produced clonic/tonic seizures and spike activity. Carbamylcholine-induced seizures were blocked by scopolamine. 5. 5. No agent was found to block antagonist-induced seizures.
