Abstract
The ultrastructural characteristics of identified dendrite bundles in the rat spinal cord were analyzed following retrograde tracing from th e soleus muscles. Dendrite bundles are arranged in networks that an he avily interconnected by means of gap junctions. The bundles are formed by at least 10 crossing dendrites travelling in different focal plane s. In between dendrites, elongated gap junctional complexes are freque ntly found. Dendrite lamellar bodies, recently described to occur in r elation with gap junctions in the central nervous system were not obse rved in the present study. (C) 1998 Elsevier Science B.V.
