A GTC #1 (blue line: normalized time course over the 20 min video) correlated significantly (cc = 0.677, p < 0.001) with the manually annotated presence of language after convolution with hemodynamic response function (red line). The statistical map projected on the brain surface reflects a linear regression with this GTC. B GTC #8 correlated with the presence of faces (cc = 0.480, p < 0.001). C and D Two GTCs yielded significant ccs with basic stimulus features extracted from the video (red line) and audio signal (yellow line; see text for details). (GTC: group temporal components; cc: correlation coefficient).
