Electron
micrograph of a large neuron (outlined by arrows) that received two
axosomatic synapses from a terminal swelling of a type II fiber. The
neuron was located at the border of the granule-cell lamina, and it gave
off a large dendrite directed toward the core of the ventral cochlear
nucleus. This dendrite receives several terminals, one of which is
darkened with HRP label. Another labeled axosomatic terminal is visible
just beneath the asterisk. The origin of that terminal could not be
determined unambiguously, but it connected with other axosomatic terminals
that also formed punctate synapses with the neuron. Together, the
terminals comprise a modified endbulb, suggesting that this neuron is a
globular bushy cell that receives input from both type I and type II
auditory nerve fibers. Scale bar =
