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. METHODS Left and right hippocampal volumes were assessed using structural magnetic resonance imaging (MRI) in 23 control subjects, 16… 
Morphological alterations in the prefrontal cortex and the amygdala in unsuccessful psychopaths.
TLDR
This study provides the first evidence of greater prefrontal and amygdala structural deficits in unsuccessful psychopaths, which may predispose them to poor behavioral control and impaired decision-making, thus making them more prone to convictions.
Abnormal hippocampal shape in offenders with psychopathy
TLDR
The results indicate that habitually violent offenders exhibit a specific abnormal hippocampal morphology, in the absence of total gray matter volume changes, that may relate to different autonomic modulation and abnormal fear‐conditioning.
Structural brain abnormalities in psychopaths-a review.
TLDR
Findings suggest that psychopathy is associated with brain abnormalities in a prefrontal-temporo-limbic circuit-i.e. regions that are involved, among others, in emotional and learning processes.
Abnormal cortical gyrification in criminal psychopathy
Localization of deformations within the amygdala in individuals with psychopathy.
TLDR
Results provide the first evidence, to the knowledge, of focal amygdala abnormalities in psychopathic individuals and corroborate findings from previous lesion studies and indicate that amygdala abnormalities contribute to emotional and behavioral symptoms of psychopathy.
Brain abnormalities in antisocial, psychopathic individuals
Since the 19th century it has been speculated that structural and functional impairment of the prefrontal cortex predisposes to antisocial, psychopathic behaviour, but it is only in the last few

Psychopathy and the posterior hippocampus
Reduced frontotemporal perfusion in psychopathic personality
Reduced prefrontal gray matter volume and reduced autonomic activity in antisocial personality disorder.
TLDR
These findings provide the first evidence for a structural brain deficit in APD and may underlie the low arousal, poor fear conditioning, lack of conscience, and decision-making deficits that have been found to characterize antisocial, psychopathic behavior.
Decreased left amygdala and hippocampal volumes in young offspring at risk for schizophrenia
Autonomic stress reactivity and executive functions in successful and unsuccessful criminal psychopaths from the community.
TLDR
It is found that successful psychopaths show increased autonomic stress reactivity and better neuropsychological function compared with unsuccessful psychopaths, and the generalizability of existing psychopathy research is discussed.
A volumetric MRI study of the hippocampus in type 1 and 2 alcoholism
TLDR
It is suggested that type 2 alcoholism, in general, similarly displays a minor decrease in hippocampal volume, but this decrease is unevenly distributed within the type 2 category, being weighted towards the younger subjects.
