Fig. 5. NA delays recovery from inactivation of T-type channels.
Current traces recorded with two pulses voltage protocol, depolarizing pulses to −20 mV from a HP = −100 mV were applied at different inter-stimulus interval (Δt), 10 ms increments for control condition (A), and 100 ms for NA (B). Time courses of recovery from inactivation (right panels) were fitted by single exponential functions with time constant (τh) of 67.6 ± 3.05 ms for control (A) and 318.01 ± 20.5 ms in the presence of 100 µM of NA (B). Error bars represent SEM (n = 9).
