Features were ranked based on the median peak score over 9 subjects. A row in the table also shows the median time point when that feature reached its peak score (medians taken over 9 subjects). All features shown were significantly predicted with p < 10-5 (corrected for multiple comparisons over features, regions, and time).
Semantic features are shown in upper case, and perceptual features in lower case.
