Anatomical and functional connections of the PVNH. A: Axial slices showing DWI connections (green) of the PVNH with nearby cortical sulci (from Fig. 2C). Resting-state time series for two subfoci of the PVNH (yellow trace) to nearby pSTS foci (orange trace) that were directly “connected” as indicated by DWI tracts. Note the high degree of comodulation of the BOLD signal over time. B: rsfMRI map of the PVNH while free from epileptiform activity. The heat map shows regions with significant comodulating activity (each session at p < 0.000001, uncorrected) in 1 (transparent red) to 5 (yellow) scanning sessions. The seed region was defined based on a T2-weighted outline within the PVNH tissue. C: Five ROIs (orange with black outline) derived from panel B revealing the functionally connected network that comodulated with the PVNH (yellow with black outline) during rest. D: Results from SVAR modeling of all six scanning data sets. E: Results from seven scans from one data set (one session) independent of those used for defining ROIs in panel C. F: Results from two scans from one of the shorter-duration data sets (400 TR measurements) used in panel C. aSTG = anterior superior temporal gyrus; Cb = cerebellum; FG = fusiform gyrus.
