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 components. This result provides the first detailed anatomical description of a neuron type unique to great apes and humans.
冯·埃科诺莫神经元是已知的类人猿皮质微回路的少数特殊结构之一。在这里，我们使用人类死后大脑的高尔基染色标本，描述了这一独特神经元群体的树突结构。我们发现，与第5层锥体神经元不同，冯·埃科诺莫神经元的树突树稀疏，顶端和基部成分对称。这一结果首次对大猩猩和人类特有的一种神经元类型进行了详细的解剖学描述。
