Cutaneous afferent fibre collaterals in the dorsal columns of the cat.

摘要: Microelectrode recordings were made from cutaneous afferent fibre collaterals in the lumbar dorsal columns of cats, which antidromically excited column at C2. The following types unit have axon ascend to nuclei; hair follicle units Types G (36.4%) and T (31.8%), slowly-adapting I (8.3%) II (5.3%) pad mechanoreceptor a few high threshold units. conduction velocities measured. All had slower than corresponding peripheral nerve fibres degree slowing was determined by class unit, with least Type most. differential confirmed recording compound action potentials various parts column-peripheral pathways.
