[Distribution and characteristics of the axonal collaterals of the rubrospinal neurons at the brain stem level].
In acute experiments on cats, intracellular recording of antidromic APs and the collision test, analysis of correlation between the time of antidromic conduction along the axon's main stem before and after collateral branching as well as the time of conduction in collaterals themselves, revealed a tendency to synchronous arrival of rubrospinal impulses to various brain stem centers at the expense of increased conduction velocity in response to lengthened distance between the brain stem structures and the red nucleus. The data obtained is discussed in the light of sensomotor integration mechanisms and role of the red nucleus in planning and actualization of the motor act.
