FIG. 3.

(Color online) δ-window distributions and comparison with response to isolated ie pairs. (a) Distribution of relative timing of i with respect to e immediately preceding a spike onset for different τ_inh. (b) The mean values of these distributions are plotted (as filled circles) as a function of τ_inh. The gray region shows the parametric dependence of the width of hypersensitive region shown in 2(b). The solid curve distinguishes two subregions where V > V_rest (gray portion with δ > t^*, see text) and where V < V_rest (δ < t^*) following an isolated inhibitory input. See text for other markings.
