[Recent acquisitions in reflexo-anesthesia]

Experimental data about the great analgetic value of electro ear-acupuncture stimulation in the cat (by prof. Durinjan--Central Research Institute for reflex-therapy--Moscow) are referred. The mechanism of analgesia by ear electro-stimulation is periacqueductal gray matter (PGM) activation. Trigeminal system as main center involved in this type of acupuncture analgesia is discussed. Up to date parameters for better analgetic results are foreseen.
