White matter (WM) is critical to cognitive function and brain activity. The objective of the present study was to test whether diffusion tensor imaging (DTI) derived WM measures are related to the cognitive event-related potential error-related negativity (ERN). Eighty-seven healthy middle-aged adults underwent DTI scanning and electrophysiological recordings while doing a version of the Eriksen flanker task. ERN was elicited in error trials. Fractional anisotropy (FA) was calculated based on… CONTINUE READING
