Points show instantaneous spike frequency during adaptation for a real ON1 in response to 400 ms duration pulse of 5 kHz (5 repetitions)(Farris et al. 2004). Black and gray curves are the double (a*e^−t/τ^fast + b*e^−t/τ^slow) and single (d*e^−t/τ) exponential fits to the data, respectively. Double exponential parameters (n = 9): τ_slow = 1054.3 ± 470.2 ms; τ_fast = 23.2 ± 13.2 ms; a = 607 ± 581; b = 188 ± 44; single exponential parameters: τ = 520 ± 171 ms; d = 235 ± 53
