Decoding the texture perception in the brain

(A) Within-modality decoding accuracy: Group statistical t-maps were obtained from non-parametric permutation-based t-test that tested whether the texture classification accuracy was above chance-level (50%) for haptic (blue), audio (yellow) or bimodal (green) decoding.

(B) Crossmodal decoding accuracy: statistical t-maps were obtained from non-parametric permutation-based t-test that tested whether the texture classification accuracy was above chance-level (50%) when the decoder was trained in Audio or Haptic condition and tested in Haptic or Audio condition respectively.

(C) Schematic illustration of the different decoding protocols. Statistical maps were voxel-level uncorrected p < 0.001 and corrected for multiple comparisons at cluster level FWE: p < 0.05 in pink or cluster-wise uncorrected p < 0.005 in purple.
