Abstract--The von Economo neurons are one of the few
known specializations to hominoid cortical microcircuitry.
Here, using a Golgi preparation of a human postmortem
brain, we describe the dendritic architecture of this unique
population of neurons. We have found that, in contrast to
layer 5 pyramidal neurons, the von Economo neurons have
sparse dendritic trees and symmetric apical and basal com-
ponents. This result provides the first detailed anatomical
description of a neuron type unique to great apes and
humans. 2006 Published by Elsevier Ltd on behalf of IBRO.
