title: Slow potentials activated by afferent and direct stimulation in spinal interneurons of laminae III-V.
abstract: Stimulation of hairy skin afferent fibers and/or direct depolarizing current injection initiates persistent changes in membrane potential (slow potentials), lasting up to 1 min or longer, in some deep dorsal horn neurons. Intracellular staining with horseradish peroxidase shows that these cells are interneurons, suggesting that slow potentials modulate moment-to-moment impulse transmission in local spinal circuits.
