Figure 7. The properties of T-type Ca2+ currents in rod bipolar cells.
(A) The T-type Ca2+ currents in rod bipolar cells were not modulated by 2 mM DTT. The currents showed more permeability to Ba2+ than to Ca2+. These T-type currents were only slightly inhibited by 20 μM Ni2+. (B) Bar graphs show the percentage change to control of T-type currents in rod bipolar cells on DTT modulation, permeability to Ca2+ versus Ba2+, and Ni2+ inhibition. Error bars indicate the SD.
