Masked Presentations of Emotional Facial Expressions Modulate Amygdala Activity without Explicit Knowledge
Functional magnetic resonance imaging (fMRI) of the human brain was used to study whether the amygdala is activated in response to emotional stimuli, even in the absence of explicit knowledge thatExpand

Response and Habituation of the Human Amygdala during Visual Processing of Facial Expression
We measured amygdala activity in human volunteers during rapid visual presentations of fearful, happy, and neutral faces using functional magnetic resonance imaging (fMRI). The first experimentExpand

The counting stroop: An interference task specialized for functional neuroimaging—validation study with functional MRI
The anterior cingulate cortex has been activated by color Stroop tasks, supporting the hypothesis that it is recruited to mediate response selection or allocate attentional resources when confrontedExpand

The emotional counting stroop paradigm: a functional magnetic resonance imaging probe of the anterior cingulate affective division
BACKGROUND The emotional counting Stroop (ecStroop) functional magnetic resonance imaging (fMRI) activation paradigm was designed to recruit the anterior cingulate affective division (ACad). Expand

Exaggerated amygdala response to masked facial stimuli in posttraumatic stress disorder: a functional MRI study
BACKGROUND Converging lines of evidence have implicated the amygdala in the pathophysiology of posttraumatic stress disorder (PTSD). We previously developed a method for measuring automatic amygdalaExpand

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 structural and functional connectivity of the amygdala: From normal emotion to pathological anxiety
The dynamic interactions between the amygdala and the medial prefrontal cortex (mPFC) are usefully conceptualized as a circuit that both allows us to react automatically to biologically relevantExpand

An fMRI study of anterior cingulate function in posttraumatic stress disorder
BACKGROUND Several recent neuroimaging studies have provided data consistent with functional abnormalities in anterior cingulate cortex in posttraumatic stress disorder (PTSD). In our study, weExpand

Human Amygdala Responsivity to Masked Fearful Eye Whites
The amygdala was more responsive to fearful (larger) eye whites than to happy (smaller) eye whites presented in a masking paradigm that mitigated subjects' awareness of their presence and aberrantExpand
