Intracranially recorded compound action potentials from the human trigeminal nerve.
Potentials from the sensory root of the trigeminal nerve in the cerebello-pontine angle, evoked by electrical stimulation of the different trigeminal divisions, were recorded during neurosurgical operations. Two components of the compound action potential could be distinguished: one early with large amplitude and one late with small amplitude. It is concluded that the two components represent activity in A alpha and A delta fibers respectively.
