TABLE 2.

Abnormal directional connectivity from the NAc to the other brain regions in tinnitus patients.

Brain region	BA	MNI coordinates	T score	Cluster size
		x, y, z (mm)
Seed: Left NAc
L inferior frontal gyrus	45	−54, 12, 24	2.8621	44
L cuneus	17	−9, −96, 0	−2.6429	41
Seed: Right NAc
L middle frontal gyrus	10	−30, 60, 15	4.1236	59
R orbitofrontal cortex	11	42,  60, −12	3.3899	75
R cuneus	17	31, −87, 3	−3.0587	45

Thresholds were set at a corrected p < 0.01, determined by Monte Carlo simulation. BA, Brodmann’s area; MNI, Montreal neurological institute; NAc, nucleus accumbens; cluster size is in cubic millimeters.
