Masked Presentations of Emotional Facial Expressions Modulate Amygdala Activity without Explicit Knowledge
This study, using fMRI in conjunction with masked stimulus presentations, represents an initial step toward determining the role of the amygdala in nonconscious processing. Expand

A large number of patients with OCD are diagnosed with at least some form of obsessive-compulsive disorder, which is still probably the least understood of all the major psychiatric syndromes. Expand
The emotional counting stroop paradigm: a functional magnetic resonance imaging probe of the anterior cingulate affective division
The ecStroop will be a useful fMRI probe of ACad function in anxiety disorders and offer a within-group spatial dissociation of AC function based upon information content (i.e., cognitive vs. emotional) and/or presence of behavioral interference. Expand
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
Anterior cingulate cortex dysfunction in attention-deficit/hyperactivity disorder revealed by fMRI and the counting stroop
The data support a hypothesized dysfunction of the ACcd in ADHD, which might contribute to producing core features of attention-deficit/hyperactivity disorder (ADHD), namely inattention and impulsivity. Expand
A symptom provocation study of posttraumatic stress disorder using positron emission tomography and script-driven imagery.
The results suggest that emotions associated with the PTSD symptomatic state are mediated by the limbic and paralimbic systems within the right hemisphere. Expand

The data support a role for dACC in reward-based decision making, and by linking the human and monkey literatures, provide initial support for the existence of heterogeneity within dACC. Expand
The Massachusetts General Hospital (MGH) Hairpulling Scale: 1. development and factor analyses.
The MGH Hairpulling Scale is developed to provide a brief, self-report instrument for assessing repetitive hairpulling and indicates that the seven items form a homogenous scale for the measurement of severity in this disorder. Expand
Organizational strategies mediate nonverbal memory impairment in obsessive–compulsive disorder
Immediate nonverbal memory problems in OCD subjects were mediated by impaired organizational strategies used during the initial copy of the Rey-Osterrieth Complex Figure Test, consistent with current theories proposing frontal-striatal system dysfunction in OCD. Expand
Functional magnetic resonance imaging of symptom provocation in obsessive-compulsive disorder.
Results of functional magnetic resonance imaging were consistent with past studies of obsessive-compulsive disorder that used other functional neuroimaging modalities, however, paralimbic and limbic activations were more prominent in the present study. Expand
