Explore how variations in brain structure and function, such as reduced amygdala volume and altered prefrontal cortex activity, shape emotional and decision-making processes. However, Sociopath Brain: Unraveling the Neurological Differences suggests that these alterations may be less pronounced in sociopaths. Since the beginning of the imaging research on psychopathy, structural abnormalities have been repeatedly reported in prefrontal, limbic, temporal, and subcortical areas. The prefrontal cortex, our brain’s CEO responsible for decision-making and impulse control, often appears to be structurally different in sociopaths. aINS = anterior insula, OFC = orbitofrontal cortex, SI = primary somatosensory cortex, SII = secondary somatosensory cortex. These differences primarily affect areas involved in empathy, decision-making, and impulse control. 11,49 Kiehl's model, the paralimbic hypothesis, has been driven by suggestions that specific brain regions share similar cytoarchitectonic features regarding neuronal type, structure and density.
