"(Medical Xpress) -- A key phenomenon studied by neuroscientists is the brain&amp;amp;#146;s ability to recognize errors when they occur, link them to the associated behavior, and apply those errors in a way that modifies the behavior - the overall goal being to optimize the intended result of engaging in that behavior. Two neural measurements &amp;amp;#150; the error-related negativity (ERN) and error-related functional MRI (fMRI) activation of the dorsal anterior cingulate cortex (dACC, sometimes referred to as the medial frontal cortex) &amp;amp;#150; have historically been seen as reflecting the same underlying neural process. Recently, however, findings by scientists at Harvard Medical School-affiliated Massachusetts General Hospital have suggested that the ERN is differentially localized to the posterior cingulate cortex (PCC)."^^<http://www.w3.org/2001/XMLSchema#string>
