Allman and his colleagues have delved beyond the level of brain infrastructure to investigate how von Economo neurons function at the superstructural level, focusing on their role as «air traffic controllers for emotions ... at the heart of the human social emotion circuitry, including a moral sense». Allman's team proposes that von Economo neurons help channel neural signals from deep within the cortex to relatively distant parts of the brain. Specifically, Allman's team found signals from the ACC are received in Brodmann's area 10, in the frontal polar cortex, where regulation of cognitive dissonance (disambiguation between alternatives) is thought to occur. According to Allman, this neural relay appears to convey motivation to act, and concerns the recognition of error. Self-controland avoidance of erroris thus facilitated by the executive gatekeeping function of the ACC, as it regulates the interference patterns of neural signals between these two brain regions.
