Global neuropathology and the regional neuropathology of six brain regions (median and range) between the pigs that developed secondary cerebrovascular pressure reactivity (PRx) peak (gray box and whiskers; n=9) and the pigs without secondary PRx peak (open box and whiskers; n=19) in the normothermia (NT) and hypothermia (HT) groups. *P<0.05 and **P<0.001. BG, basal ganglia; CM, cerebellum; GM, gray matter; HI, hippocampus; Path, global neuropathology; TH, thalamus; WM, white matter.
