The effect of somatic potassium channels on the shift of the peak ITD. Activation of potassium currents reduced responses but did not affect the position of the peak ITD (EE+K). Increasing the strength of sodium currents moved the peak ITD to the ipsilateral-leading side (EE+Na+K); increasing inhibition (Gi = 11 nS) moved the peak ITD to the contralateral-leading side (EE+Na+K+I). Identical ionic channels were used for the soma and the axon membrane, with the exception of the density of sodium channels; GNa was 0.2 S/cm2 on the soma and 0.3 S/cm2 on the axon.
