Abstract
1. The EEG of Gallus domesticus was recorded before and after brain lesions following stimulation with light, sound and taste. 2. It was found that under the conditions of the experiment the lesions did not have any general effect on the arousal mechanism of the animal. 3. Bilateral lesions in the stratum cellulare externum of one animal had a specific effect on the arousal response to a quinine hydrochloride solution and it was concluded that it is possible to indicate deficits following brain lesion in the gustatory system using the EEG.
