Fig. 9.

Site and direction specificity of response interactions as revealed by simultaneous stimulation at 2 different locations. The spatial location of the 2 stimuli, and their directions of motion, interacted to produce a variety of idiosyncratic responses. Responses to motion at the fixed direction sites presented alone are shown as colored asterisks. Responses to motion at the probe sites alone are shown as black diamonds. Two-segment responses are plotted in the probe location's segment as colored diamonds with the color corresponding to that used for the fixed direction component.
