Figure 6. Ion channels and receptors that mediate high‐speed transmission are expressed in bcan^−/− mice .

Coronal sections of the ventral lower brainstem dimensioned to include the entire MNTB show the respective immunoreactivity in adult bcan ^+/+ (left) and bcan ^−/− mice (right). The rostrocaudal planes of sections in the two genotypes are matched; midline to the left. K_v3.1β (A), Ca_v2.1 (B), and GluR4 (C); positive immunoreactivity to the antibodies against all three cellular components is seen in the overview staining and in the blow‐ups in both genotypes. Scale bar in all MNTB overviews = 100 μm and scale bar in all high magnification inserts = 10 μm.
