Effects of SCS on responses of lumbosacral spinal neurons to noxious CRD (60 mmHg, 20s). A: L2-L3 SCS suppressed the excitatory response of a spinal neuron to CRD. B: L2-L3 SCS did not affect the inhibitory response of a spinal neuron to CRD. C: C1-C2 SCS suppressed the excitatory response of a spinal neuron to CRD. D: C1-C2 SCS did not significantly affect the inhibitory response of a spinal neuron to CRD.
