[The collateral branching of the axons of efferent neurons in the cat parietal cortex]. / Kollateral'noe vetvlenie aksonov éfferentnykh neironov temennoi kory koshki.

Collateral branching of efferent neurons' axons in the cat parietal associative cortex was studied with intracellular recording of antidromic activity. Specific features of the axon collaterals projecting onto the sensorimotor cortex, pontine nuclei proper and red nucleus, were revealed and described. Information arriving from the parietal cortex simultaneously at the above two motor structures suggests their interrelationship to be actualized through the axon collaterals of efferent neurons. This kind of functional interrelationship of the structures via axon branching of efferent neurons of the parietal cortex provides synchronous arrival of signals at the structures participating in motor integration.

[Neuronal reactions of the central cerebellar nuclei in the waking cat to cortical and peripheral stimuli]. / Reaktsii neironov tsentral'nykh iader mozzhechka bodrstvuiushchei koshki na korkovye i perifericheskie stimuli.

Neuronal responses of the central cerebellar nuclei to electrical stimulation of the cerebral cortex and electrocutaneous stimulation of the limbs were studied in alert cats. An obvious responsiveness of neurons of the fastigial nucleus to the peripheral signals and impulses from the motor cortex was found. The neurons of the n. interpositus responded preferably to peripheral stimuli and signals from the somatosensory cortex. The responses of the medial part of the lateral nucleus to peripheral signals are described, as well as neuronal responses of the lateral nucleus to impulses from the association parietal cortex.
