From: Relating a calcium indicator signal to the unperturbed calcium concentration time-course
Reverse reconstruction of the calcium influx from the indicator signal. a: Calcium influx α(t) (in black) together with the reconstructed influx (in red). b: Optimal forward filter gforw(t). c: Average time course of calcium-bound indicator y(t) (in black), reconstructed signal (in red), and 12 individual indicator signals (in grey). d: Optimal reverse filter grev(t).
