Projection of Afferent Fibers From the Knee Joint to the Cerebellum of the Cat

Abstract

Studies were made of projection of articular afferents to the cerebellar cortex in 19 cats. Joint nerves were stimulated, cerebellar potentials recorded and various incisions made in the cervical cord in attempts to modify or abolish the evoked potentials. The results show that there are crossed and uncrossed paths in each ventral and lateral region of the cord. Impulses can reach either cerebellar hemisphere by any one of these paths. Impulses may cross at brain stem and cerebellar levels and there is evidence that spino-olivary and spinoreticular, as well as spinocerebellar, fibers are concerned.
