Responses of example neurons in area 1 to type 2 plaids. A. Component gratings at −30° and −60° and resulting type 2 plaid (veridical direction = 0°). B. Responses of a neuron in area 1 to these plaids scanned in each of 16 directions. C. Preferred direction (PD) of this neuron for each grating/plaid morph. D. Mean preferred direction of all significantly direction-tuned area 1 neurons (red) and perceived direction (blue) for each grating/plaid morph; 26 out of 45 area 1 neurons were sensitive to the direction of motion of the −30°/−60° plaids E. Component gratings at −30° and −75° and resulting type 2 plaid (veridical direction = 0°). F. Responses of a neuron in area 1 to plaids (with components separated by 45°) scanned in each of 16 directions. G. Preferred direction of this neuron for each grating/plaid morph. H. Mean preferred direction of all significantly direction-tuned area 1 neurons (red) and perceived direction (blue) for each grating/plaid morph; 16 out of 32 area 1 neurons were sensitive to the direction of the −30°/−75° plaids.
