A bi-exponential conductance response function. This response runction is reset whenever a new event arrives. That is, all memory of previous events is lost and the response starts again from the beginning. For a response which persists independent of further spikes, use the CumulativeResponseFunction.
When a spike arrives on the input port, an conductance change is triggered in the attached membrane with the given riseTime, fallTime, maximal conductance (conductance), reversal potential, Erev and total duration. For a smooth profile, the duration should be several times the decay time. If the decay time is set to be smaller than the rise time it will be ignored and an alpha function (x * exp(-x/tau)) will be used. This is the limiting form of a bi-exponential as the decay time approaches the rise time from above.
Any number of response functions may be applied to the same component.
