Figure 8.

Large dendrite (LD) that received a synapse (arrowheads in panels A and B) from a type II axon. The dendrite could not be traced to its soma, but its large diameter makes it distinct from the small dendrites of Figure 3. C The same large dendrite, in another section, also receives an unlabeled synapse with a robust postsynaptic density and with four postsynaptic bodies (between arrows), which is a synapse typical of those formed by medial olivocochlear branches (see text). Part of a granule cell (g) is indicated. In all panels, the asterisk denotes an axon with a relatively constant orientation relative to the large dendrite. Scale bar = 1 μm.
