# VERHULST2018 - Cochlear transmission-line model (improved, incl. brainstem)

## Usage

output = verhulst2018(insig,fs,fc_flag)
[output, cf] = verhulst2018(insig,fs,fc_flag, ...)


## Input parameters

 insig the input signal to be processed. Each column is processed in parallel, so it is possible to run several simulations in parallel fs sampling rate [Hz] fc_flag list of frequencies specifying the probe positions along the basilar membrane, or 'all'to probe all 1000 cochlear sections, or 'abr' to probe 401 locations between 112 and 12000 Hz.

## Output parameters

 cf center frequencies of the probed basiliar membrane sections output structure with the following fields: v velocity of the basilar membrane sections v(time,section,channel) y displacement of the basilar membrane sections y(time,section,channel) oae ottoacoustic emission as sound pressure at the middle ear fs_an sample rate of the an output fs_abr sample rate of the brainstem sections (IC,CN and W1/3/5 outputs) ic output of the IC cn output of the CN anfH HSR fiber spike probability [0,1] anfM MSR fiber spike probability [0,1] anfL LSR fiber spike probability [0,1] an_summed sum of HSR, MSR and LSR per channel, i.e., the input to the CN ihc IHC receptor potential w1 wave 1 w3 wave 3 w5 wave 5

## Description

This function computes the basilar membrane displacement and the velocity of the movement at different positions.
