The cerebellum has been implicated to form an inverse dynamic model of a control object. Purkinje cells (PCs), the sole output cell type of the cerebellum, are thought to encode motor commands for their control object that are conformed by cerebellar synaptic plasticity to minimize errors in motor performance. Thus a question arises: Can the PCs that control a biological motor system, such as the eyes, acquire appropriate motor commands to drive a non-biological motor system, such as a direct current (DC) motor? We utilized a vestibulo-ocular reflex (VOR) motor learning scheme. Single unit recording of vestibulo-cerebellar PC's was conducted in goldfish. The desired trajectory of a DC motor was given to the fish in the form of head rotation. The PC firing rate modulated by the vestibular stimulus was converted into a pulse width modulation signal in real time to drive the DC motor. The produced DC motor trajectory was subtracted from the desired trajectory to calculate a performance error. The error signal was fed-back onto the goldfish retina as whole-field visual image motion. This activates VOR motor learning, and lets us evaluate if the PC under recording can improve the performance of the DC motor. The performance error of the DC motor under the VOR motor learning scheme was reduced adaptively. The result suggests that the cerebellum can acquire an internal model of a non-biological motor system, and a single PC is capable of adaptive motor control. |
