a statistical trendp = .075
A statistical trend was found between HN and Con ( p = .075, corrected), showing that HN also had more brain activity than Con (M = 1.9*10 −12 , SD = 3.86*10 −12 ). 3.4 Associations between symptoms and source activity A significant negative cluster over the right frontal and medial sensors was found in the cluster-based regression analysis, t (37) = −1.788, p = .041, β = −0.282 (see Fig. 4 A), indicating that in SZ, higher positive symptoms are related to lower levels of alpha power in these sensors.
