Functional organization of marsupial visual cortex

In their Science Advances publication, Young Jun Jung et al. with Michael Ibbotson’s lab at the National Vision Research Institute (NVRI) determined that marsupials’ visual cortices are organized like cats and primates, not like rodents and rabbits. Recordings with NeuroNexus 32-channel probes (A1x32-6mm-100-177-A32 and A4x8-5mm-100-200-177-A32 or A4x8-5mm-100-400-177-A32) enabled creation of single-unit adjacency maps. Their results demonstrate that orientation preference in the wallaby primary visual cortex is organized in a pinwheel.
