Heterogeneity of non-conscious fear perception in posttraumatic stress disorder as a function of physiological arousal: An fMRI study
journal contribution
posted on 2023-05-17, 07:15 authored by Kemp, AH, Kim FelminghamKim Felmingham, Falconer, E, Liddell, BJ, Bryant, RA, Williams, LMWhile posttraumatic stress disorder (PTSD) is often characterised by an excessive fear response and hyperarousal, research has generally neglected other clinical characteristics including hypoarousal. Findings indicate that concurrent autonomic activity is associated with increased non-conscious processing of fear, highlighting that autonomic responsivity may be an important determinant in the degree of activation within the brainstem-amygdala-MPFC (medial prefrontal cortex) network.
