[Spatial organization of tissue elements of the caudate nucleus in the dog].

Simple methods for quantitative analysis of nerve cells and their processes in n. caudatus of dog are suggested. Some principal features of the internal arrangement of n. caudatus are established and correlated with other brain system. Graphic reconstruction of small cells ensembles and their distribution within the nucleus is given. Physiological role of small cell ensembles and large caudate cells (long axoned and short axoned) for caudatocortical transmission of excitation is considered.
