IMPLICATIONS: Isoflurane, halothane, and propofol depress spinal neurons in the ventral horn, but not the dorsal horn, in the 0.8 1.2 minimum alveolar anesthetic concentration range. These data suggest that immobility likely occurs as a result of anesthetic action on ventral neurons, presumably motoneurons, central pattern generators, and premotor interneurons.
