Coherence maps before (a,c) and after (b,d) six-months treatment in delta band (a,b) and in theta band (c,d) during the responding to joint attention (RJA) task. Maps show an increase of inter-hemispheric frontal-parietal delta coherence (pink boxes) and a reduction of theta band in occipital areas (green boxes), and in frontal areas (yellow boxes) as well as an increase of theta band in parietal regions (red boxes). Coherence data are represented as a matrix in which electrodes are displayed on the x and y axes. Elements of the matrix represent color-coded coherence values between electrodes.
