The influence of optokinetic nystagmus upon the auditory cortical evoked potentials

Research output: Contribution to journalArticle


Ebersole and Galambos (1969) reported that in cats during the fast phase of the optokinetic nystagmus (ON) the amplitude of the click-elicited auditory cortical evoked potentials (EP) also decreased. They suggested that 'something like a corollary discharge' could be responsible for this effect and the present experiment is aiming to test this idea, namely in relation to the active, following slow phase of the ON. Our results indicate that the input to the auditory cortex may be depressed during the slow following eye movement which would indicate a selective attention effect. As those effects were observed only in half of the animals it calls for caution in making conclusions about the possible physiological role.
