Outline of Final Research Achievements

The aims of this study are to examine how neuronal population represents visual information in the mouse visual cortex and how the neuronal representation is affected by behavioral context such as visual discrimination task. We recorded visual responses to natural images from mouse primary visual cortex and revealed that diverse visual response properties of individual neurons enable representation of natural image with small number of neurons. We also trained mice on a discrimination task of moving-grating direction and compared visual responses during the task with those outside the task. Preliminary results suggest that visual responses were modulated during the task.
