Outline of Final Research Achievements |
We conducted wide-field one-photon and high-resolution two-photon calcium imaging in premotor (PMdc) and primary motor (M1) cortices of common marmosets while they learned a two-target reaching (pull/push) task. Throughout learning, PMdc switched its preferred movement direction, whereas M1 neurons stably retained it. This result suggests that the motor representation changes in PMdc would be required for the learning of a sensorimotor association learning.
