A functional connection in the fronto-parietal system shows reliable differences between impaired and non-impaired patients. Student’s t-tests between impaired and non-impaired patients results in a single functional connection between frontal-parietal regions with a correlation strength difference, non-impaired more correlated than impaired, that meets the stringent Bonferroni correction for multiple comparisons. The left frontal (−41, 20, 31) to right parietal (41, −55, 45) connection, shown on a translucent brain in 2 views (left panel posterior view; right panel dorsal view) has mean standardized R of 0.346 for non-impaired and 0.118 for impaired (p = 0.00001).
