title: [Descending pathways of the cerebral cortex to nuclear structures of the extrapyramidal system].
abstract: The connections of the neocortical structures in animal and human brains with the complex of nuclear formations of the extrapyramidal system have been studied. The authors present comparative characteristics and distribution of these connections in the nuclear and other formations of the extrapyramidal system. Both mediator (via the thalamus) and direct cortical projections toward the nuclei of the extrapyramidal system in primates, especially in humans, have been found to increase. It has been shown that the frontal cortex has closer connections with the complex of the extrapyramidal nuclei as compared with other brain lobes.
