Fig. 4.
The bar graph depicts the current density of the barium currents in wild-type and leaner Purkinje cells. The total barium current densities intgla/tglacells were reduced compared with tgla/+ cells (gray bars; p < 0.01). There was no significant difference between the current densities of the ω-AgTx-IVA-resistant currents (the current remaining after ω-AgTx-IVA block; black bars) intgla/+ andtgla/tglacells. The mean current density of the ω-AgTx-IVA-sensitive current (striped bars) intgla/tglacells was 65% smaller than that intgla/+ cells (p≪ 0.0001).
