Cortical responses to the motion-defined rotating wedge stimulus (single subject, single session, averaged across the eight eye positions). Time series from each voxel were fit with sinusoids with period equal to that of the stimulus rotation. A, Amplitude of the best-fitting sinusoid indicates the amplitude of the cortical response. B, Phase angle of the best-fitting sinusoid indicates the stimulus position that elicited the largest response. Responses have been projected onto a computationally flattened representation of the subject's right hemisphere. White lines indicate visual area boundaries defined in an independent retinotopic mapping session.
