- Title
Behavioral and neural effects of chromatic isoluminance in the primate visual motion system.

- Abstract
We have previously reported that the responses of individual neurons in macaque visual area MT elicited by movement of contrast-reversing heterochromatic red/green borders are largest when the two hues are “balanced” or isoluminant (Dobkins & Albright, 1994). This “neural” isoluminant point was found to vary somewhat across the sample of neurons. Here, we compare the average neural isoluminant point in area MT to a behavioral measure of isoluminance, obtained using a modification of an oculomotor procedure developed by Chaudhuri and Albright (1992). These behavioral estimates of isoluminance closely parallel the neuronal data obtained from area MT. In accordance with previous evidence (e.g. Lee et al., 1988; Kaiser et al., 1990; Valberg et al., 1992), this correlation suggests that activity within the dorsal/magnocellular stream underlies behavioral expression of chromatic isoluminance.
