Relationship between white matter integrity and subcortical response to TMS. Using deterministic tractography, the tract between FP1 and the left putamen was isolated and the average FA values along the tract were compiled for each individual (A). As a group, there was a significant positive relationship between FA value along the tract and TMS-evoked BOLD signal in the striatum bilaterally (B). Individuals with higher tract integrity had a larger effect of TMS in these afferent targets of the frontal pole. A scatter plot shows the relationship between FP1 to putamen fractional anisotropy and cluster beta values after controlling for age, TMS pulses administered, diffusion protocol, and scalp to cortex distance (C).
