Abstract
Trauma re-experiencing is often dominated by recollection of sensory-perceptual elements of the trauma, pointing to involvement of the sensory thalamus. This study examined re-experiencing symptoms in relation to volumes of thalamic nuclei implicated in sensory information processing. We hypothesized that re-experiencing, controlling for other posttraumatic symptom dimensions, would be significantly associated with volumes of the pulvinar nuclei (visual salience), ventroposterolateral nuclei (VPL: somatosensory), and lateral and medial geniculate nuclei (LGN, MGN: primary visual and auditory relays).
