Functional organization for shape and texture in macaque visual area V4

Recognizing object shape and their surface texture is a remarkable feature of our visual system. Visual area V4 is an intermediate stage of visual object processing in the non-human primate brain. Many neurons in visual area V4 encode information about the shape and texture features of visual stimuli. However, how the functional organization across cortical laminae in visual area V4 for these stimulus features is unknown. We studied the responses of dozens of neurons simultaneously recorded across laminae while monkeys performed passive fixation against a 2D shape silhouettes and textures. In my talk, I will introduce latest results from this experiment.
