Effects of temporal precision of inhibition in the point model. A, Effects of the time constant τi of inhibition. The peak position of the ITD function is greatly influenced by the brief (τi = 0.1 ms), but not by the relatively long, inhibition. Parameter values are Ge = 2 nS for excitation and Gi = 10, 2, and 2 nS for inhibition with τi = 0.1, 0.5, and 1 ms, respectively. Inhibition leads excitation by 0.2 ms. B, Effects of relative timing of inhibition. The shift of the ITD function is more prominent when inhibition leads excitation by ∼0.1 ms. Parameter values are Ge = 2 nS, Gi = 10 nS, and τi = 0.1 ms. Parameters marked with asterisks are those used in the model of Brand et al. (2002). ipsi, Ipsilateral; contra, contralateral.
