Evidence for Acquired Pregenual Anterior Cingulate Gray Matter Loss from a Twin Study of Combat-Related Posttraumatic Stress Disorder
BACKGROUND Controversy exists over the nature and origin of reduced regional brain volumes in posttraumatic stress disorder (PTSD). At issue is whether these reductions represent preexistingExpand

Voxel-based analysis of MRI reveals anterior cingulate gray-matter volume reduction in posttraumatic stress disorder due to terrorism
MRI studies using the manual tracing method have shown a smaller-than-normal hippocampal volume in patients with posttraumatic stress disorder (PTSD). However, these studies have yielded inconsistentExpand

Aging in the CNS: Comparison of gray/white matter volume and diffusion tensor data
This study investigated the global and regional effects of aging on brain volume, mean diffusivity (MD), and fractional anisotropy (FA) in 73 normal female subjects using voxel-based analysis. On aExpand

Smaller amygdala volume and reduced anterior cingulate gray matter density associated with history of post-traumatic stress disorder
Although post-traumatic stress disorder (PTSD) may be seen to represent a failure to extinguish learned fear, significant aspects of the pathophysiology relevant to this hypothesis remain unknown.Expand

Voxel-based diffusion tensor analysis reveals aberrant anterior cingulum integrity in posttraumatic stress disorder due to terrorism
Recent functional neuroimaging work has suggested that interregional functional connectivity between the anterior cingulate cortex (ACC), other limbic, and prefrontal regions may be involved in theExpand

Amyotrophic lateral sclerosis: diffusion tensor tractography and voxel‐based analysis
The purpose of this study is to investigate whether the diffusional anisotropy of water molecules is disrupted in the pyramidal and extra‐pyramidal regions in patients with amyotrophic lateralExpand

Localized volume reduction in prefrontal, temporolimbic, and paralimbic regions in schizophrenia: an MRI parcellation study
Functional and structural abnormalities of the anterior cingulate gyrus (ACG) in patients with schizophrenia have been repeatedly reported. However, one remaining issue is whether gray matter volumeExpand

Association Between the Oxytocin Receptor Gene and Amygdalar Volume in Healthy Adults
BACKGROUND Recent studies have suggested that oxytocin affects social cognition and behavior mediated by the oxytocin receptor (OXTR) in amygdala in humans as well as in experimental animals. GeneticExpand

Human brain structural change related to acute single exposure to sarin
This study aimed to identify persistent morphological changes subsequent to an acute single‐time exposure to sarin, a highly poisonous organophosphate, and the neurobiological basis of long‐lastingExpand

Sexually dimorphic gray matter volume reduction in patients with panic disorder
While clinical features of panic disorder show significant sexual dimorphism, previous structural MRI studies have not sufficiently controlled for sex when looking at regional brain abnormalities inExpand
