Rodent studies have proposed that adolescent susceptibility to substance use is at least partly due adolescents experiencing reduced aversive effects of drugs compared adults. We thus investigated methamphetamine (meth) conditioned place preference/aversion (CPP/CPA) in and adult mice both sexes using a high dose meth (3 mg/kg) or saline as controls. Mice tagged with green-fluorescent protein (...
INTRODUCTION Among the functional neuroimaging studies on emotional face processing in schizophrenia, few have used paradigms with facial expressions of disgust. In this study, we investigated whether schizophrenia patients show less insula activation to macro-expressions (overt, clearly visible expressions) and micro-expressions (covert, very brief expressions) of disgust than healthy controls...
Interoceptive awareness (IA), the subjective and conscious perception of visceral physiological signals from body, has been associated with functions cortical subcortical neural systems involved in emotion control, mood anxiety disorders. We recently hypothesized that IA its contributions to mental health are realized by a brain interoception network (BIN) linking regions receive ascending inte...
The human insula has been the focus of great attention in the last decade due to substantial progress in neuroimaging methodology and applications. Anatomical support for functional localization and interpretations, however, is still fragmented. The aim of the present study was to re-examine the microanatomical organization of the insula and relate cytoarchitectonic maps to major sulcal/gyral p...
BACKGROUND Conjoint activity of the insula and amygdala has frequently been reported during emotional stimulation in general and in anxiety-related contexts in particular. However, direct connectivity between the insula and amygdala in this framework has received little attention so far. Studying whether inter-individual differences in anxiety reflect variation in insula-amygdala connectivity i...
