Co-activation of the amygdala, hippocampus and inferior frontal gyrus during autobiographical memory retrieval.
Functional MRI was used to investigate the role of medial temporal lobe and inferior frontal lobe regions in autobiographical recall. Prior to scanning, participants generated cue words for 50 autobiographical memories and ...
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 ...
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. ...
Altered resting-state functional connectivity of basolateral and centromedial amygdala complexes in posttraumatic stress disorder.
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 ...
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 ...
