The neural generators of the vestibular evoked response

Abstract A new method for the induction and recording of a short-latency vestibular evoked response (VsER) to intense acceleration impulses with skin electrodes was studied in cats. The first two waves, P 1 and P 2 , had latencies of 2.5 and 3.5 ms, respectively, and coincided with the recorded gross neural activity in the vestibular nerve and nuclei, respectively. Single second-order vestibular neurons with low and irregular activity responded to the same acceleration impulses with a latency as short as 3.5 ms.
