Convergence of V2a interneurons onto single motoneurons. (a) Intracellular injection of neurobiotin into a slow motoneuron resulted in dye-coupling in V2a interneurons. (b) Number of segmental and intersegmental V2a interneurons dye-coupled to single slow motoneurons (n = 5 motoneurons from separate animals, error bars reflect the s.e.m.). (c) V2a interneurons dye-coupled to an intermediate motoneuron. (d) Number of segmental and intersegmental V2a interneurons dye-coupled to single intermediate motoneurons (n=5 motoneurons from separate animals, error bars in the graph reflect the s.e.m.). (e) V2a interneurons dye-coupled to a fast motoneuron. (f) Number V2a interneurons converging onto single fast motoneurons (n=5 motoneurons from separate animals, error bars in the graph reflect the s.e.m.). Scale bars, 20 µm
