BACKGROUND Major damage to gray and white matter in the prefrontal cortex and autonomic deficits have been found to result in pseudopsychopathic personality in patients with neurological disorders, but it is not known whether people with antisocial personality disorder (APD) in the community who do not have discernable brain trauma also have subtle(More)
BACKGROUND Although studies of neurologic patients have suggested that prefrontal structural impairments may predispose to sociopathy, it is unknown whether there is a relationship between psychopathy and prefrontal volume in individuals from the community and whether any prefrontal structural impairment is specific to "unsuccessful" (caught) psychopaths as(More)
BACKGROUND Structural and functional hippocampal abnormalities have been previously reported in institutionalized psychopathic and aggressive populations. This study assessed whether prior findings of a right greater than left (R > L) functional asymmetry in caught violent offenders generalize to the structural domain in unsuccessful, caught psychopaths.

CONTEXT Despite the repeated findings of impaired fear conditioning and affective recognition in psychopathic individuals, there has been a paucity of brain imaging research on the amygdala and no evidence suggesting which regions within the amygdala may be structurally compromised in individuals with psychopathy. OBJECTIVE To detect global and regional(More)
Although deficits in several cortical and subcortical structures have been found in psychopaths, it remains unclear whether the neuropathology differs between subgroups of psychopaths (i.e., unsuccessful and successful). Using both traditional and novel image analyses methods, this study aims to reveal gross and subtle morphological changes in the(More)
Finger movement-related responses were identified in three discrete sites of mesial frontal cortex in 7 normal subjects using high resolution functional magnetic resonance imaging. During imagination of the same movements there was a differential response with rostral areas more active than caudal areas. Humans have multiple motor areas in mesial frontal(More)
CONTEXT Psychopathic antisocial individuals have previously been characterized by abnormal interhemispheric processing and callosal functioning, but there have been no studies on the structural characteristics of the corpus callosum in this group. OBJECTIVES To assess whether (1) psychopathic individuals with antisocial personality disorder show(More)
Abnormal temporal and prefrontal cortical gray matter thinning in psychopaths Psychopathy is a complex clinical condition conceptualized as a combination of personality features, including shallow affect and egocentricity, as well as behavioral features including impulsivity and poor behavioral controls. 1 It has been hypothesized that deficits in the(More)
BACKGROUND Magnetic resonance neurography (MRN) is an imaging method by which nerves can be selectively highlighted. Using commercial software, the authors explored a variety of approaches to develop a three-dimensional volume-rendered MRN image of the entire brachial plexus and used it to evaluate the accuracy of infraclavicular block approaches. METHODS(More)
Advances in cardiac device technology have led to the first generation of magnetic resonance imaging (MRI) conditional devices, providing more diagnostic imaging options for patients with these devices, but also new controversies. Prior studies of pacemakers in patients undergoing MRI procedures have provided groundwork for design improvements. Factors(More)
