5 days ago · April 21, 2024. in Neuroimaging. Photo credit: NIDA. Individuals with stronger depressive symptoms and those who experienced stressful life events tend to show alterations in volume of the nucleus acumbens, according to new research. Additional changes in the volume and functional connectivity of specific brain regions were also observed.
2 days ago · We find that MDMA robustly enhances both the social transfer of pain and analgesia and that the drug’s action in the nucleus accumbens (NAc) core alone is sufficient to produce these effects. Moreover, optogenetic stimulation of serotonin (5-HT) inputs in the NAc core similarly enhances empathy, suggesting a key role for MDMA-mediated 5-HT ...
3 days ago · The potential therapeutic role of DBS in SE-AN was also assessed in a case report by Arroteia et al., where they described impressive weight gain in a 42-year-old woman suffering from chronic and treatment-resistant AN (bulimic subtype) after 12 months of bilateral Nucleus Accumbens (NAcc) DBS .
