[Reduction of the bloodflow in the vestibular centre].
The little writing of nystagmus or "petite écriture" is a very striking observation in the examination of the vestibular function by means of the pendular test. The "petite écriture" can be found in patients with reduction of the bloodflow in the vestibular centre. The "petite écuriture" has an average amplitude of 3.5 degrees during the high pendular acceleration (15-18 degrees sec2). It seems to be a variation of the central nystagmus-typ (écriture centrale) found after more effective irritations of the vestibular centre for example encephalitis or contusion of the brainstem.
