Research Abstract |
We examined how the thamalo-striatal system involves the process of selection with the undesirable action when the monkeys biased the desirable action. Striatum neurons encoded response bias and specific action combined with reward size before and after instruction epoch. The thalamic CM neurons were related to cancellation of response bias when the monkeys required the undesirable action. Thus, the thamalo-striatal system might involve in biasing toward action based on the reward value and cancellation when unexpected situation was occurred.
