In the cortex of carnivore and primate model species, specific sensory features are encoded into functional maps. It remains unclear how the layout and interrelations of functional maps observed from surface layer activity generalize to deeper cortical layers. Cortical functional maps can be identified using electrophysiology with high temporal but spatially sparse sampling, impeding a holistic understanding of functional organization. Optical imaging can provide spatially extended sampling of cortical activity, but optical access is limited to about 1 mm depth, i.e. cortical layer 2/3 in larg
