Abstract

An intravenous injection of 0.85 mg/kg strychnine nitrate produced typical convulsions in all cockerels, aged 4 to 12 weeks, as well as adult hens. Convulsions consisted of an initial excitement, tonic stage associated with opisthotonos, transient clonic movement, and finally vigorous tonic convulsions. Strychnine spikes in the Wulst EEG were not induced by the same intravenous does of strychnine in both cockerels and adult hens.
