Based upon initial experimental series demonstrating that electroanalygesia EA stimulation trains are capable of attenuating cortical activity of probable significance in pain perception, two definitive experimental series have been initiated to quantitatively assess neurological mechanisms and clinical effectiveness. The neurological experiments are based upon electrophysiological characterizations of EA currents at the levels of primary receptors, primary nerve conduction, and intermodality gating interactions in primary afferents from tooth pulp. The results are summarized. The human experiments are based on pulp vitalometry procedures adapted to the practical and analytical constraints of signal detection theory. The results to date are discussed.
