LUTEar 2.0.9 Manual

Models

There is also a basic format which all the modules in the Model group follow: (i) set parameters and (ii) run model. Like the stimulus modules, the particular parameters for these modules may be set individually, with a single routine call or they can be read from a parameter file. These modules also work using EarObjects. They expect to have a signal piped to their input signal (they complain if it is not) and generate the model output to the output signal. All the model module file names are prefixed with, "Mo".

MoBasilarM:
The routines for the basilar membrane filter bank are to be found in this module. It uses the gamma tone filter routines to be found in the "UtFilters" module

Mo4BasilarM:
This module is the non-linear Stone 4 composite filter. It uses the gamma tone and IIR filter routines to be found in the "UtFilters" module.

MoDendrite:
A low-pass filter is used to model the dendritic effect. The module uses routines from the "UtFilters" module.

MoHairCell:
This module implements the Meddis86 inner hair cell (IHC) model.

Mo2HairCell:
This is the implementation of the Meddis 93 stochastic IHC model. There has been a separation of the receptor potential actions and the subsequent processing, as previously appeared in the Meddis 86 IHC model. It requires input from the inner hair cell receptor potential module.

MoMgGregor2:
This module implements a version of the McGregor neural cell model. It expects spike input from the auditory nerve.

MoPreEmph:
The outer/middle-ear model is implemented by this modules. It calls the band pass filter routines to be found in the "UtFilters" module.

MoRecptPotn:
The inner hair cell receptor potential actions has been decomposed from the Meddis 86 IHC model. This module implements a model of the receptor potential behaviour. It is required as input to the Meddis 93 stochastic hair cell.

MoSpikeGen:
This module is used to convert the spike probability output from the Meddis 86 IHC model to summed stochastic events, as observed from the auditory nerve.
