The laminar structure of cortex was first described by Ramón y Cajal (1899). It consists of six different layers, each containing a characteristic distribution of neurons and cell types connecting with other cortical and sub-cortical regions. These extensive connections form microcircuits that group into functionally distinct columns (e.g. Mountcastle, 1997). To account for the Venetian Blind Effect, Cao and Grossberg propose a model which exploits the functional organization of visual cortex, in particular the selective firing activities of visual cortical neurons responding to the orientation and/or the luminance contrast of surface boundaries, demonstrated first by Hubel & Wiesel (1959 and 1962).
