Immunohistochemical assessment of the phenotype of the organ of Corti by using the synaptic vesicle marker anti-CSP (red) and the nuclear stain DAPI (blue) in midbasal cochlear turns in WT and BKα–/–, 4 and 14 weeks. CSP staining is noted in IHCs and efferent synapses. Note the reduced CSP immunoreactivity at the OHC but not IHC level in BKα–/– animals at 14 weeks. (Bar = 20 μm.)
