| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The vestibule-ocular reflex (VOR) has been one of the most popular model systems to investigate the role of the cerebellum in adaptive motor control. VOR motor learning is induced by continuous application of head rotating stimulus combined with optokinetic visual stimulus. For instance, in-phase application of those stimuli increases VOR gain defined by eye velocity of VOR in the dark divided by head velocity, while out-of-phase application of those decreases VOR gain. Recently, it was reported that performance of the VOR is modifiable context-dependently. Namely, VOR gain can be increased for leftward head rotation, while it can be decreased for rightward head rotation simultaneously. This instance implies the possibility that the cerebellum flexibly processes context dependent input signals. In the VOR motor learning, it is considered that long term depression and long term potentiation at the synapses between parallel fibers and Purkinje cells play a key role. Moreover, it has been revealed that different modality of input signals of VOR are tuned for gain increase and gain decrease learning. Cerebellar signal processing underlying context dependent motor learning, however, is not fully uncovered. Presently, we conducted a simulation study on context dependent VOR motor learning, using the artificial cerebellar neuronal network model that we developed to understand the origin of the flexible cerebellar motor learning. | |
