The ocular-dominance column
borders in upper (2, 3) and lower
(5, 6) layers are blurred,
compared to the sharp
boundaries in layer 4. The
arrows illustrate electrode
tracks made in layer 4 (upper
left) and layer 2 or 3 (upper
right). The lower diagrams plot
ocular dominance of cells
recorded along the tracks. In
layer 4, we find abrupt
alternation between group 1
(contralateral eye only) and
group 7 (ipsilateral eye only). In
other layers, we find binocular
cells, and the eye dominance
alternates by going through the
intermediate degrees of eye
preference. (1, 4, and 7 refer to
ocular dominance.)
Viewed from the side, the
subdivisions in layer 4 appeared
as patches. But we wanted to
know how the pattern would
appear if we stood above the
cortex and looked down.
