Comparison of data and models. A, Predicted response pattern for head-centric flow model. B, Predicted parallel response lines for retino-centric flow model. C, Amplitudes of the measured BOLD responses in experiment 2, averaged across all subjects. Data from each subject were corrected for the pursuit bias and normalized with respect to the mean response amplitude. Error bars indicate ±1 SEM. D, Interaction with eye position predicts identical responses for consistent and opponent pursuit that differ from the responses during fixation. Values in gray are head-centric rotation speeds (in degrees per second). Ordinate scaling in A, B, and D is in arbitrary units.
