Fig 1. Illustration of the postsynaptic kernels used in this analysis, and an example of a resulting postsynaptic membrane potential.

(A) The time course of the postsynaptic current kernel α. (B) The PSP kernel ϵ. (C) The reset kernel κ. (D) The resulting membrane potential u_i as defined by Eq (1). In this example, a single presynaptic spike is received at t_j = 0 ms, and a postsynaptic spike is generated at t_i = 4 ms from selectively tuning both the synaptic weight w_ij and firing threshold ϑ values. We take C = 2.5 nF for the neuron’s membrane capacitance, such that the postsynaptic current attains a maximum value of 1nA.
