title: Complex spike responses of cerebellar Purkinje cells to constant velocity optokinetic stimuli in the cat flocculus.
abstract: In the cat cerebellar flocculus without cerebrum but with intact accessory optic tract, complex spike (CS) responses to horizontal optokinetic stimuli (velocity-step at 2 degrees/s) were investigated. The directionally selective CS responses were present only during the short-duration stimuli but not during the continuous unidirectional stimuli. Following the end of the stimuli during the stationary surround phase, the CS activity was modulated in a manner opposite to the preceding CS response during the stimulation. These CS responses cannot simply be interpreted as sensory responses to the retinal slip input; they may in fact be deeply associated with the motor control command of the eye movement which would be elicited by the retinal slip.
