Instrument for the on-line measurement of the slow phase of nystagmus.
The on-line measurement of the slow-phase velocity of vestibular nystagmus, induced or spontaneous, has considerable practical advantages. An instrument for this purpose, developed around simple operational amplifiers, is described. Typical applications of the system are given in respect of nystagmus induced by optokinetic, rotational, and caloric stimuli.
