Resting-state functional connectivity Group comparisons of interhemispheric motor cortex BOLD signal r -coefficients, including all ROI pairs, resulted in highly significant K–S differences ( D ) between ALS and healthy participants ( D = 0.19, p < 7 × 10 −26 ) with ALS being less connected overall than healthy controls (see Figures 3 and 4 ).
