Comparative molecular neuroanatomy of mammalian neocortex

Unlike inhibitory neurons, there had been few good antibodies to classify the excitatory neurons, which resulted in the comment that “chemical diversity of neurons in the neocortex is mainly a feature of the population of nonpyramidal cells.” (DeFelipe 1993).
