How are the complex maps for feature selectivity created in the mammalian visual cortex? In most Eutherian mammals (e.g. cats, ferrets, tree shrews, and primates), orientation selective cells are organised into columns, which are arranged in pinwheel-like patterns across the cortex. However, rodents and rabbits do not have the same cortical structure: although they have robust orientation selectivity (OS) in individual cells, these are randomly distributed across the cortex in salt-and-pepper maps. Many studies have tried to explain how the complex maps for orientation preference (OP) are created in the primary visual cortex (V1). However, it remains unknown why some mammals have random salt..
