<unk> s, also called von Economo neurons (VENs), are a specific class of neurons that participate in signal transmission in the nervous system, and are characterized by a large<unk> -shaped soma, gradually tapering into a single apical dendrite (axon) in one direction, with only a single dendrite facing opposite.  Whereas other types of neurons tend to have many dendrites, the polar shaped morphology of<unk> s is unique, having only been found in two very restricted regions in the brains of hominids - the family of species comprising humans and great apes. A recent study, however, has found<unk>  cells in the brains of the humpback whales, fin whales, killer whales and sperm whales.  The name von Economo neuron comes from their discoverer, Constantin von Economo (1876-1931).
