Document Summary
Columnar organization cells in v1 are grouped into (at least) 3 types of columns: location, Described the functional org of primary visual cortex. Each column is coding for a different region of visual space. Cells w/in a given column are all coding for the same location in visual space. These cells all have overlapping receptive fields. W/in each location column there are two ocular dominance columns. Cells within a given column respond best to stimuli at a given location as seen thru a given eye (either right or left) W/in each location and od column, there are several orientation columns. Each column codes an orientation; every ~10 deg of angle is coded by a diff column. Cells within a column code the same orientation. A chunk of v1 tissue decoted to the feature analysis of a specific region of visual space. Consists of 1 location column, 2 ocular dominance columns, and a complete set of orientation columns.
