Do primary afferents from tooth-pulp cross the midline?
Compound action potentials were recorded from the pulps of canine teeth in cats during stimulation of the inferior dental nerve, trigeminal ganglion or brain stem on one side. Recordings were also made from the inferior dental nerve while stimulating the canine pulps. No evidence for pulpal fibres crossing the midline was found.
