The basic structure of the neocortex in insectivorous bats (Miniopterus sthreibersi and Pipistrellus pipistrellus). A Golgi study.

A Golgi study of the neocortex of Miniopterus sthreibersi and Pipistrellus pipistrellus revealed the presence of pyramidal cells distributed in an orderly fashion and many types of local-circuit neurons including small, medium-size and large multipolar cells with smooth dendrites and generalized axonal arborizations, double-bouquet neurons, chandelier cells, spiny stellate cells in midlevel of the cortex, sparsely spined multipolar neurons with ascending axons and horizontal cells of layer VI. In addition, extraverted neurons of layer II widely branching into the molecular layer and giant multipolar cells with very long and smooth dendrites embracing the whole cortical thickness distinguished the organization of the neocortex in these primitive species.
