hypercolumn

A complete set of orientation columns over a cycle of 180º and of right and left dominance columns in the visual cortex. A hypercolumn may be about 1 mm wide. A hypercolumn of orientation columns is perpendicular to a hypercolumn of ocular dominance columns (Fig. H5). See blobs; cortical column." >Fig. H5 A hypercolumn consisting of one set of orientation columns and one set of ocular dominance columns in the visual cortex. Electrode 1 penetrating at right angle to the surface encounters neurons responding to the same orientation and the same (right) ocular dominance
