Effects of CS system electrical stimulation on developing CS axon terminations. A, B. Horizontal sections through the deep dorsal horn. CS axon terminals are labeled using horseradish peroxidase conjugated to wheat germ agglutinin (white dots). Stimulation (A) results in a bilateral distribution of terminations while only contralateral terminations are in the control (B). C. Effect of unilateral stimulation on the non-stimulated CS system (C1) showing a dorsal shift in the terminations compared with the control (C2). BDA was used to label the non-stimulated axons. (Salimi and Martin, 2004) Calibrations. A, B, C. 1 mm.
