(A) Anterior View and (B) Superior View of Correlation Maps Between Frequency Mismatch Negativity (MMN) Recorded at frontal-central and Measures of Frontal Gray Matter. r Values are thresholded at P < .05 (uncorrected) and confirmed to be significant by permutation testing for both hemispheres at P < .05. (C) Low levels of sociooccupational functioning ratings (Social and Occupational Functioning Assessment Scale [SOFAS]) are correlated (P < .05, 1 tailed) with lower MMN amplitudes to frequency deviants in schizophrenia subjects.
