Neuron_DendriteLP: Dendritic Filtering


File name
MoDendrite.[ch]


Description
Dendritic filter model. It converts summed spike events into a form useable by neural cells, using a low-pass filter. It is used as input to the neural cell models, working with hair cell output.


Example parameter file format
300.0	Cut-off frequency (3 dB down point - Hz).
33.0	Pulse height for one spike (?).



Test program directory
Tests/SSPrograms

Generic Module Routines

This module has the standard Generic Module Routines (see Basic Module Routines used in Generic Programming, page 52).

The RunModel_Neuron_DendriteLP(...) Process Routine

Syntax
BOOLN RunModel_Neuron_DendriteLP(EarObjectPtr data);


Returns
TRUE if the process is successful, otherwise it returns FALSE.

The SetCutOffFrequency_Neuron_DendriteLP(...) Routine

Syntax
BOOLN SetCutOffFrequency_Neuron_DendriteLP(double theCutOffFrequency);


Returns
TRUE if the function is successful, otherwise it returns FALSE.

The SetPars_Neuron_DendriteLP(...) Routine

Syntax
BOOLN SetPars_Neuron_DendriteLP(double theLowerCutOffFreq, double theSignalMultiplier);


Returns
TRUE if the function is successful, otherwise it returns FALSE.

The SetSignalMultiplier_Neuron_DendriteLP(...) Routine

Syntax
BOOLN SetSignalMultiplier_Neuron_DendriteLP(double theUpperCutOffFreq);


Returns
TRUE if the function is successful, otherwise it returns FALSE.
