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.
