FIGURE 5

The Kir3.2 channel subunit is differentially expressed along the somatodendritic axis of hippocampal principal cells. (A) Representative electron micrographs of spiny dendrites from str. oriens (Ori), radiatum (Rad) and L - M (L - M) of the CA1. Immunogold labeling for the Kir3.2 channel subunit seen as 10 nm gold particles. Spines and fractured spine necks are indicated with asterisks (∗). Scale bar: 200 nm (top row), 100 nm (bottom row). (B) Summary bar charts of the surface density for the Kir3.2 subunit from the different layers of the CA1 (left), CA3 (middle), and DG (right) are shown alongside representative images of principal cells. Mean surface densities are overlain by measurements of individual density values for examined structures. Statistics shown: ns = P > 0.05, *P < 0.05, one-way ANOVA.
