Images are thresholded at a reduced uncorrected P = 0.001. A: in the SN, connectivity within the paraventricular nucleus of the hypothalamus (PVN) was correlated with resting BI. B: likewise, SN connectivity within the midbrain [periaqueductal gray (PAG)], pons [parabrachial nucleus (PB)], and medulla [rostral ventral lateral medulla (RVLM)] was also positively correlated with resting BI. Note also connectivity with the precuneus. D, dorsal; V, ventral.
