Perfusion-based functional connectivity maps of six insular subdivisions (R-vAI, R-dAI, R-PI, L-vAI, L-dAI, L-PI) in mTBI + PTH patients (mTBI patients with PTH, n = 48) and mTB-PTH patients (mTBI patients without PTH, n = 46). L, left; R, right; vAI, ventral anterior insula; dAI, dorsal anterior insula; PI, posterior insula
