Distinctive Neurons of the Anterior Cingulate and Frontoinsular Cortex: A Historical Perspective. A New Type of Special Cells of the Cingulate and Insular Lobes

Abstract

Human anterior cingulate and frontoinsular cortices participate in healthy social-emotional processing. These regions feature 2 related layer 5 neuronal morphotypes, the von Economo neurons and fork cells. In this paper, we review the historical accounts of these neurons and provide a German-to-English translation of von Economo's seminal paper describing the neurons which have come to bear his name. We close with a brief discussion regarding the functional and clinical relevance of these neurons and their home regions.
