Detailed Description

Piecewise linear additive spike response.

The shape of the spike response is defined by an array of amplitudes $(a_1,...,a_N)$ and an array of time spans $(d_1,...,d_N)$. The PSP amplitude at time $t_1 = 0$ after a spike was triggered is $a_1$, that at time $t_n = d_1 + d_2 + ... + d_{n-1}$ is $a_n$. The PSP amplitudes are linearly interpolated between $t_{n}$ and $t_{n+1}$. The PSP amplitudes between $t_{N}$ and $t_{N+1}$ are constant $a_{N}$. If a spike occurs while the response is active the overlapping spike responses are added up.
