Research Overview

We develop cognitive tasks for the common marmoset. We use fluorescent imaging methods to measure the dynamics of the neuronal activity in the marmoset cerebral cortex during the task performance. We also use optogenetics and chemogenetics to manipulate the neuronal activity during the task performance to reveal the causal relationship between the task-relevant activity and behaviors.
