  • For each experiment, the first line gives the parameters used in Equation 4 to fit g for the rising phase of the firing rate, and the second line gives the parameters used for the decay phase. Corresponding values of the slope and delay parameter for these experiments: α = 5.1; δ = 18 msec (10297); α = 4.7; δ = 27 msec (10797); α = 6.3; δ = 25 msec (10897); α = 6.3; δ = 28 msec (12897).
