The Auditory Modeling Toolbox
KELVASA2015_ANPROCESSING - AN model used in Kelvasa and Dietz 2015 binaural model
Usage
[APvec] = kelvasa2015_anprocessing(electrodogram, vTime);
Input parameters
| electrodogram | N x M matrix of electrode current values in (microA) with N being the number of CI electrodes and M being a time vector with 1/pulse rate/maxima sampling frequency |
| vTime | time vector in seconds with M samples |
Output parameters
| APvec | N x 2 matrix of AN spikes with Nx1 holding indices of the spiking neuron and Nx2 holding corresponding spike time in seconds. |
KELVASA2015_anprocessing(insig,fs,varargin) computes auditory nerve spike times over a given population of AN fibers using a simulated electrode nerve interface as detailed in (Fredelake & Hohmann (2012))
