Abstract: Neurophysiological responses of cats are frequently studied in an attempt to understand perceptual and physiological responses of men.The purpose of the present experiments i s to compare nystagmus responses o f man and cat to equivalent vestibular stimuli to provide a basis for comparative interpretation of data. FINDINGSNystagmus in alert cats declined during prolonged constant angular acceleration, whereas nystagmus i n alert men did not decline under similar conditions.The rate of decline of primary nystagmus after application o f each stimulus was greater in cats than in man.The ratio of secondary to primary nystagmus was higher in cat than in man.All of these effects may be manifestations of a central process which tends to suppress prolonged primary vestibular reactions.In cats this process influences nystagmic reactions which may be closely connected to sensory perceptions.In man, this process is evident by its influence on sensory perception and i s not clearly manifest in nystagmic reactions of alert men.
