Consistency of preferences between physical and ambiguous motion. (A) Qualitative consistency. Preferences for either horizontal (red) or vertical (green) motion are shown on the transverse slice of a selected subject (S1, left area hMT+) during either physical (left) or ambiguous (right) motion. Perceptually brighter colors indicate a higher degree of preference. Preferences are overlaid on segmentation labels of white (light-gray voxels) and gray matter (dark-gray voxels). (B) Quantitative consistency. Displayed are the median bootstrapped correlation coefficients for t values of the contrast horizontal > vertical found for physical and ambiguous motion. Voxels were selected based on independent data from the hMT+ localizer. Every point represents the result of a single subject (S1, S3, S7, S8, and S9). Error bars represent the 2.5th and 97.5th percentile of the bootstrapped correlation coefficients.
