Abstract
Vertically oriented bundles of apical dendrites in the cat motor cortex were studied by methods of light and electron microscopy. The presence of desmosome-like and dendro-dendritic contacts in the bundles is regarded as the structural basis for electrotonic interaction between neurons in the same column. Axo-spinous "en passant" contacts between the descending axon of the pyramids of layer III and the apical dendrite of pyramids in layer V, possibly serving to regulate the activity of the principal cortical output elements, are described.
