Recall of Fear Extinction in Humans Activates the Ventromedial Prefrontal Cortex and Hippocampus in Concert
BACKGROUND Extinction of conditioned fear is thought to form a new safety memory that is expressed in the context in which the extinction learning took place. Rodent studies implicate theExpand

Convergence and Segregation of Ventral Striatal Inputs and Outputs
ABSTRACT: The ventral striatum, which prominently includes the nucleus accumbens (Acb), is a heterogeneous area. Within the Acb of rats, a peripherally located shell and a centrally situated core canExpand

A functional magnetic resonance imaging study of amygdala and medial prefrontal cortex responses to overtly presented fearful faces in posttraumatic stress disorder.
BACKGROUND Previous functional neuroimaging studies have demonstrated exaggerated amygdala responses and diminished medial prefrontal cortex responses during the symptomatic state in posttraumaticExpand

The Cortical Signature of Alzheimer's Disease: Regionally Specific Cortical Thinning Relates to Symptom Severity in Very Mild to Mild AD Dementia and is Detectable in Asymptomatic Amyloid-Positive
Alzheimer's disease (AD) is associated with neurodegeneration in vulnerable limbic and heteromodal regions of the cerebral cortex, detectable in vivo using magnetic resonance imaging. It is not clearExpand

A functional MRI study of human amygdala responses to facial expressions of fear versus anger.
Functional magnetic resonance imaging (fMRI) of the human brain was used to compare changes in amygdala activity associated with viewing facial expressions of fear and anger. Pictures of human facesExpand

Differential prefrontal cortex and amygdala habituation to repeatedly presented emotional stimuli
Repeated presentations of emotional facial expressions were used to assess habituation in the human brain using fMRI. Significant fMRI signal decrement was present in the left dorsolateral prefrontalExpand

Inhibited and Uninhibited Infants "Grown Up": Adult Amygdalar Response to Novelty
Infants with an inhibited temperament tend to develop into children who avoid people, objects, and situations that are novel or unfamiliar, whereas uninhibited children spontaneously approach novelExpand

Basal amygdaloid complex afferents to the rat nucleus accumbens are compartmentally organized
The basal amygdaloid complex (BAC) topographically projects to the nucleus accumbens (Acb) in patchy, inhomogeneous patterns. These termination patterns may be related to the histological features ofExpand

Neuroanatomical correlates of extraversion and neuroticism.
Introversion/extraversion and neuroticism are 2 important and frequently studied dimensions of human personality. These dimensions describe individual differences in emotional responding across aExpand

A functional MRI study of amygdala responses to angry schematic faces in social anxiety disorder
Neuroimaging studies using angry or contemptuous human facial photographic stimuli have suggested amygdala hyper‐responsivity in social anxiety disorder (SAD). We sought to determine if an angryExpand
