Figure 2.

Shape-tuning test. A, Example neuron 1. Average net responses are plotted as a function of stimulus dimensions. Top row from left to right, Vertical curvature, horizontal curvature, vertical tapering, and horizontal tapering. Bottom row from left to right, Aspect ratio, orientation, and center-of-mass. Solid lines, Large shapes; dotted line, small shapes. The inset shows the average response during saccades toward the RF (solid line) and saccades outside the RF (dotted lines) aligned to stimulus onset in the target-cue test. B, Example neuron 2. Same conventions as in A.
