After it was learned that electroanesthesia (EA) could not be produced in a Rhesus monkey which had undergone a circumferential scalp block with 0.25% lidocaine, it was postulated that EA could be produced by electrostimulation of the sensory nerves of the scalp in the rhesus. The work reported here verifies that EA can be produced by this method in this species; it is not necessary to pass current through the head.
