Figure 5

Photomicrographs of endbulbs of cats stained by antibodies directed against the vesicular glutamate transporter (Vglut1), alongside corresponding drawings to illustrate the individual swellings that were drawn and measured. (A) Representative endbulbs from a normal hearing cat. Note the high density of small swellings that encircle the equator of the cell body. (B) Typical staining from a congenitally deaf cat, where the number of swellings around the cell body is greatly reduced. These images of Vglut1-stained endbulbs resemble those of HRP-labeled endbulbs illustrated in Figure 3. (C) Usual images of endbulbs from congenitally deaf cat that received 2–3 months of electrical stimulation through a cochlear implant. The increased number of swellings around the cell body implies that activity restored the endbulb arborization. Scale bar equals 10 µm.
