Specificity of Color Connectivity Between Primate V1 and V2. J. Neurophysiol. 82: 2719-2730, 1999. To examine the functional interactions between the color and form
pathways in the primate visual cortex, we have examined the functional
connectivity between pairs of color oriented and nonoriented V1 and V2
neurons in Macaque monkeys. Optical imaging maps for color selectivity,
orientation preference, and ocular dominance were used to identify
specific functional compartments within V1 and V2 (blobs and thin
stripes). These sites then were targeted with multiple electrodes,
single neurons isolated, and their receptive fields characterized for
orientation selectivity and color selectivity. Functional interactions
between pairs of V1 and V2 neurons were inferred by cross-correlation
analysis of spike firing. Three types of color interactions were
studied: nonoriented V1/nonoriented V2 cell pairs, nonoriented
V1/oriented V2 cell pairs, and oriented V1/nonoriented V2 cell pairs.
In general, interactions between V1 and V2 neurons are highly dependent
on color matching. Different cell pairs exhibited differing
dependencies on spatial overlap. Interactions between nonoriented color
cells in V1 and V2 are dependent on color matching but not on receptive field overlap, suggesting a role for these interactions in coding of
color surfaces. In contrast, interactions between nonoriented V1 and
oriented V2 color cells exhibit a strong dependency on receptive field
overlap, suggesting a separate pathway for processing of color contour
information. Yet another pattern of connectivity was observed between
oriented V1 and nonoriented V2 cells; these cells exhibited
interactions only when receptive fields were far apart and failed to
interact when spatially overlapped. Such interactions may underlie the
induction of color and brightness percepts from border contrasts. Our
findings thus suggest the presence of separate color pathways between
V1 and V2, each with differing patterns of convergence and divergence
and distinct roles in color and form vision.
