Values of the a − d constants used in Eqs 1–3 for the excitatory and inhibitory neurons used in the model of the auditory brain.

Neuron Type refers to model neurons reported by [21]. a: time scale of u(t). Smaller values mean slower recovery. b: sensitivity of u(t) to subthreshold fluctuations in v(t). Larger values result in subthreshold oscillations and low-threshold spiking. c: after-spike reset value of v(t). d: after-spike reset value of u(t).
