The encoding model and the regressors that are used in deconvolution. (a) The encoding model. The stimulus is first processed with a nonlinear function and then the processed stimulus is used as the input \(x\) (i.e., regressor). The EEG data is considered as the output \(y\). The ABR or AEP is the impulse response from the linear kernel and can be derived by deconvolving the EEG data and the regressor. (b) Regressor generation process. Upper, the half-wave rectified stimulus (HWR). Lower, the Auditory Nerve Modeled firing rate (ANM). IHC = inner hair cell, AN = auditory nerve, HSR = high spontaneous rate, CF = characteristic frequency.
