| Research Abstract |
As an association cortex, inferotemporal cortex is the final stage of the ventral cortical pathway which is critical for object recognition and object discrimination. To investigate the functional organization of the cortical area, the optical imaging based on intrinsic signals is thought to be a powerful technique. However, although the optical imaging simultaneously records the activity for a large population of cells in a relative wide cortical area, the method to analyze the causal relationship across the local regions in the imaged area is not yet available. In the present study, we have succeeded in the separation between the component of optical signal induced by the presentation of the stimulus and that independent on the stimulus presentation, and proposed a method to emphasize the activity relationship.
