[f. hyper- 6 + column n.]
An array of columns of neurons in the visual cortex of the brain, which processes the visual information conveyed by its constituent columns to provide a particular item of more complex information.
1974Hubel & Wiesel in Jrnl. Compar. Neurol. CLVIII. 302/2 It seems useful to extend the concept of the column... For the orientation system this would be a full set of slabs subserving an entire 180° cycle, while for the ocular dominance system it would be a left-eye column plus a right-eye column. We may refer to such a group as a hypercolumn. 1979J. P. Frisby Seeing iii. 41/1 Although the hypercolumns are distributed evenly over the cortical surface, hypercolumns concerned with the central retina differ from those dealing with the periphery in having smaller hyperfields. 1983Fortune 24 Jan. 84/3 A given hypercolumn might report in effect: ‘I have a moving line in my sector, slanted at a 45° angle, with red on the left side of the line and blue on the right.’ |
