FMRI responses and decoding results in color patches in the chromatic and achromatic gratings viewing experiment.

<p>(A) Averaged fMRI responses elicited by chromatic and achromatic gratings, which were not used to define color patches, in color patches across all 3 subjects. (B) Chromatic and achromatic decoding accuracy when training the classifier to distinguish among the 3 chromatic/achromatic gratings in N-1 runs and testing on the left-out run. Black asterisks indicate a significant difference from the chance level (0.333 in B, indicated by the dash lines), and red ones indicate a significant difference between chromatic and achromatic gratings; *q < 0.05, **q < 0.01, ***q < 0.001.
