Acute effects of trauma-focused research procedures on participant safety and distress
(Psychiatry Research, 2014-01-30)The ethical conduct of research on posttraumatic stress disorder (PTSD) requires assessing the risks to study participants. Some previous findings suggest that patients with PTSD report higher distress compared to non-PTSD ... -

Altered resting-state functional connectivity of basolateral and centromedial amygdala complexes in posttraumatic stress disorder.
(Neuropsychopharmacology, 2014-01)The amygdala is a major structure that orchestrates defensive reactions to environmental threats and is implicated in hypervigilance and symptoms of heightened arousal in posttraumatic stress disorder (PTSD). The basolateral ... -
Amygdala volume changes in posttraumatic stress disorder in a large case-controlled veterans group.
(Arch Gen Psychiatry, 2012-11)CONTEXT: Smaller hippocampal volumes are well established in posttraumatic stress disorder (PTSD), but the relatively few studies of amygdala volume in PTSD have produced equivocal results. OBJECTIVE: To assess a large cohort ... -
Brain activity during episodic retrieval of autobiographical and laboratory events: an fMRI study using a novel photo paradigm.
(J Cogn Neurosci, 2004-11)Functional neuroimaging studies of episodic memory retrieval generally measure brain activity while participants remember items encountered in the laboratory ("controlled laboratory condition") or events from their own life ... -
Emotion-attention network interactions during a visual oddball task.
(Brain Res Cogn Brain Res, 2004-06)Emotional and attentional functions are known to be distributed along ventral and dorsal networks in the brain, respectively. However, the interactions between these systems remain to be specified. The present study used ... -
Emotional intensity predicts autobiographical memory experience.
(Mem Cognit, 2004-10)College students generated autobiographical memories from distinct emotional categories that varied in valence (positive vs. negative) and intensity (high vs. low). They then rated various perceptual, cognitive, and emotional ... -
Examining the Role of Lateral Parietal Cortex in Emotional Distancing Using TMS.
(Cognitive, affective & behavioral neuroscience, 2020-10)We recently proposed a neurocognitive model of distancing-an emotion regulation tactic-with a focus on the lateral parietal cortex. Although this brain area has been implicated in both cognitive control and self-projection ... -
Neural responses to emotional involuntary memories in posttraumatic stress disorder: Differences in timing and activity.
(NeuroImage. Clinical, 2018-01)Background:Involuntary memories are a hallmark symptom of posttraumatic stress disorder (PTSD), but studies of the neural basis of involuntary memory retrieval in posttraumatic stress disorder (PTSD) are sparse. The study ... -
Neural systems for guilt from actions affecting self versus others.
(Neuroimage, 2012-03)Guilt is a core emotion governing social behavior by promoting compliance with social norms or self-imposed standards. The goal of this study was to contrast guilty responses to actions that affect self versus others, since ... -
Reduced hippocampal and amygdala activity predicts memory distortions for trauma reminders in combat-related PTSD.
(J Psychiatr Res, 2011-05)Neurobiological models of posttraumatic stress disorder (PTSD) suggest that altered activity in the medial temporal lobes (MTL) during encoding of traumatic memories contribute to the development and maintenance of the disorder. ... -
The short and long of it: neural correlates of temporal-order memory for autobiographical events.
(J Cogn Neurosci, 2008-07)Previous functional neuroimaging studies of temporal-order memory have investigated memory for laboratory stimuli that are causally unrelated and poor in sensory detail. In contrast, the present functional magnetic resonance ... -
The spatiotemporal dynamics of autobiographical memory: neural correlates of recall, emotional intensity, and reliving.
(Cereb Cortex, 2008-01)We sought to map the time course of autobiographical memory retrieval, including brain regions that mediate phenomenological experiences of reliving and emotional intensity. Participants recalled personal memories to auditory ...
