Identification of tonically active neurons located in the anatomical equivalent of the MLR and muscle tone suppression during SubCR stimulation. A, Inhibition of MLR tonically active neuron during lumbar perivertebral pressure evoking bilateral hindlimb muscle tone suppression. B, Bilateral hindlimb muscle tone inhibition during SubCR electrical stimulation (R, right side). C, Ipsilateral hindlimb muscle tone inhibition during SubCR electrical stimulation (right side). MLR(R), Tonically active MLR unit (right side). See abbreviations in Figure 1.
