Figure 5.

MVPA results, MEG source-space analysis in A1 (top) and V1 (bottom). The traces depict decoding accuracy over time (red = accuracy exceeds the statistical significance threshold; 0 ms = stimulus onset; post-stimulus vertical line = time when the decoding accuracy first becomes significant; grey shade = SEM across subjects). Decoding for unimodal stimuli starts in sensory-specific cortices (left column) and emerges faster in A1 than in V1. Cross-sensory decoding for unimodal stimuli (middle column) occurs later, followed by audiovisual interactions for bimodal stimuli (right column). Time scale –100 to +500 ms post stimulus, stimulus duration 300 ms, analysis time window length 50 ms, time window sliding step 1.7 ms.
