Hypercolumn is a term used in neuroscience to describe a group of neurons in the neocortex that respond to specific features of a visual stimulus. To describe this group of neurons, several synonyms can be used such as cortical module, functional column, ocular dominance column, or orientation column. These terms all refer to the organization of neurons in the neocortex based on their functional properties. The term "hypercolumn" was first coined by David Hubel and Torsten Wiesel in 1979, and since then, many studies have focused on understanding the role of hypercolumns in visual perception. Synonyms for hypercolumn are helpful for researchers to communicate their findings and insights on this neural structure.
