Cover legend: Three-dimensional reconstructions of part of the left cerebellum (lobules V, simple lobule and crus 1) of the rat showing precise matching of mossy fiber terminals (green) and climbing fiber terminals (red) both labeled from an injection into the paramedian lobule. Mossy fibers in addition terminate in nonadjacent band-like patterns. Yellow contour: cerebellar surface, cyan: Purkinje cell layer, blue: white matter.
