The mean time constant at the base of the outer segment (τb) and the tip of the outer segment (τt), and the tip/base time constant ratio are reported. All values are mean ± SEM for a number of cells, n.
Student’s t test demonstrates a statistically significant difference between whole cell control solution (0 mM NADPH) and whole cell (5 mM NADPH); P < 0.005.
