Deep white matter integrity according to ASR habituation response. Relationship between auditory startle reflex habituation (ASR) and the deep white matter integrity assessed by DTI imaging, showing a higher fractional anisotropy [FA_deep, left, main effect of ASR habituation, F(1,53) = 4.9, P = 0.0306] and lower mean diffusivity [MD_deep, right, F(1,53) = 3.4, P = 0.0693] in patients with extinguishable response (EX) compared to patients with inextinguishable response (IN). Post hoc testing revealed a significant effect (P < 0.05 uncorrected) only in vegetative (VS/UWS) patients. *P < 0.05.
