Abstract There may be different neural bases between subjects with epilepsy only (EP) and interictal chronic epilepsy psychosis (EPS). However, there have been few structural MRI studies of EPS. The current study was conducted to investigate the neural substrate of EPS. T1-weighted images were analyzed in 14 patients with EPS and 14 strictly-matched patients with EP. We conducted volume comparison in the whole brain using voxel-based morphometry (VBM). The VBM method revealed that EPS patients exhibited significantly reduced gray matter volumes in the left postcentral gyrus and the left supra marginal gyrus compared with EP patients (adjusted p = 0.029, FDR corrected q; k = 319 voxels). For clinical correlations, there were no significant associations between psychotic symptoms and gray matter volumes in the left postcentral gyrus and the left supra marginal gyrus. VBM analysis revealed that reduced gray matter volumes in the left postcentral gyrus and the left supra marginal gyrus may be crucial regions for EPS.

Antisocial Tendencies

Psychopathic traits predispose individuals toward antisocial behavior. Such antagonistic acts often result in 'unsuccessful’ outcomes such as incarceration. What mechanisms allow some people with relatively high levels of psychopathic traits to live ‘successful’, un-incarcerated lives, in spite of their antisocial tendencies? Using neuroimaging, we investigated the possibility that ‘successful’ psychopathic individuals exhibited greater development of neural structures that promote ‘successful’ self-regulation, focusing on the ventrolateral prefrontal cortex (VLPFC). Across two structural MRI studies of ‘successful’ participants (Study 1: N = 80 individuals in long-term romantic relationships; Study 2: N = 64 undergraduates), we observed that gray matter density in the left and right VLPFC was positively associated with psychopathic traits. These preliminary results support a compensatory model of psychopathy, in which ‘successful’ psychopathic individuals develop inhibitory mechanisms to compensate for their antisocial tendencies. Traditional models of psychopathy that emphasize deficits may be aided by such compensatory models that identify surfeits in neural and psychological processes.
