TL;DR: The results show that PTSD may be associated with alterations in the broader hippocampal network, and associations between PTSD and disrupted white matter organization measured by lower fractional anisotropy in the tapetum region of the corpus callosum.

TL;DR: It is indicated that cortical volumes in PTSD patients are smaller in prefrontal regulatory regions, as well as in broader emotion and sensory processing cortical regions.
Journal ArticleDOI
Interaction of temporal and ordinal representations in movement sequences.
TL;DR: The results confirm the presence of an independent representation of temporal structure and advocate a nonlinear multiplicative neural interaction of temporal and ordinal signals in the production of movements.
Journal ArticleDOI

TL;DR: In patients with DPD, the structural connectivity between brain regions crucial for multimodal integration and emotion regulation may be altered and a trend for 1 subnetwork is found that may support the model of frontolimbic dysbalance suggested to underlie DPD symptomatology.
Journal ArticleDOI
Does trauma-focused psychotherapy change the brain? A systematic review of neural correlates of therapeutic gains in PTSD
TL;DR: In this paper, a meta-analytic results indicate that posttraumatic stress disorder (PTSD) is associated with hypoactivation of the medial prefrontal cortex (mPFC), hyper activation of the amygdala, and volume reductions of the hippocampus.
