Immunohistochemical labeling of synaptic endings using VGLUT1 antibodies identifies excitatory synaptic contacts on an MSO dendrite of a cat with normal hearing. a: Cross-section through a dendrite shows four labeled endings (white asterisks) and one unlabeled ending (black asterisk). One labeled ending (double asterisks) is magnified in panel b, where an asymmetric postsynaptic density (arrow) and round SVs are consistent with the ending's inferred excitatory nature. Scale bars = 2 μm in a; 500 nm in b.
