Abstract:
Cognitive tasks such as mental arithmetic and fixation of imagined targets are known to affect vestibular nystagmus. Here we show that another cognitive task-subject's active control of the rotation of a single moving visual line in an otherwise darkened room-influences the gain of the torsional optokinetic response to that single moving visual line.
