Outline of Final Research Achievements

There were two technical challenges that need to be overcome. First goal was to establish a method to express GCaMP in marmoset cortical neurons at a level sufficient for in vivo imaging. We accomplished this goal by finding an appropriate promoter for driving GCaMP expression in marmoset neurons. Second goal was to have columner level functional mapping over marmoset visual cortex. We confirmed that traditional intrinsic signal optical imaging can meet this goal. We further established a wide-field calcium imaging technique that far exceed the intrinsic signal imaging in both temporal resolution and signal to noise ratio. Combination of these two techniques will enable functional mapping of top down signal in the marmoset visual cortex.
