Fig. 2.
The right insula structural coupling with the ACC and its relationship to ‘prosociality’. (a) Grey matter regions showing significant correlations with intensity in the right insula were rendered in the MNI space (n = 135) (voxel threshold: uncorrected P < 0.001). L, left; R, right. (b) Scatter plots depicting correlations between the coupling of the right insula with anterior cingulate and ‘prosociality’ in males, indicating that subjects with weak relationship between these two structures have highly autistic traits in the social domain.
