Development of vestibulo-ocular response in the kitten.
Vestibulo-ocular response (VOR) has been recorded in kittens aged between 10 and 61 postnatal days. Responses to velocity steps and to sinusoidal oscillations are present on the earliest recordings, though they are limited to a low gain slow compensatory gaze displacement. Vestibular-induced saccades appear only around postnatal day 30, but adult-like responses with a high gain are not displayed before the end of the second month. Optokinetic nystagmus (OKN) appears earlier (around postnatal day 25) and maturates faster.
