| Research Abstract |
To explore the mechanism of acquisition, retention and expression of motor learning, we investigated roles of the cerebellar cortex and the vestibular nuclei which receive information from the cerebellar cortex. When information transmission from the cerebellar cortex to the vestibular nuclei was blocked, score of motor learning was low. However, when the information transmission was recovered at the second learning test, the score was high. On the contrary, after inducing the motor learning at the first learning test of normal information transmission, the score remained high at the second learning test of blocked information transmission. These results suggest that the cerebellar cortex is necessary for expression of motor learning but not necessary for expression after establishment of the motor learning.
