Convolution-based approach for removal of ionic artifacts. (A) Waveform used for measurements with a small-amplitude prepulse placed in front of every FSCV sweep. (B) Typical step response measured at carbon-fiber microelectrode. (C) Typical impulse response estimate obtained from the discrete differentiation of the step response in panel B. (D) Figure showing a measured background current (green) and the corresponding prediction (orange) generated using convolution of the impulse estimate in panel C with the FSCV waveform. (E) Residual current after subtraction of the prediction for the data shown in panel D.
