[Impulsive angular acceleration evoked middle and long latency potentials in guinea pigs].

Abstract

Middle and long latency evoked potentials have been successfully recorded in guinea pigs with impulsive angular acceleration delivered by a specially developed motor. The middle latency responses elicited by impulsive angular acceleration had peaks at about 9 ms, 15 ms and 24 ms with a mean peak to peak amplitude of about 28muV and the long latency responses after the delivering of impulsive angular acceleration in guinea pigs composed of a triphasic wave with a mean peak to peak amplitude of about 50 muV occurring during 32 ms to 130 ms with respect to the start of head stimuli. A series of experiments lead to the conclusion that the middle latency responses to impulsive angular acceleration are middle latency vestibular evoked potentials. The long latency response elicited by impulsive angular acceleration is not a specific response of auditory or vestibular pathway.
