| Description
|
This
module is the Meddis 86 inner hair cell module. The parameters A and
B have been changed so that the hair cell responds correctly for
intensity levels in dB (SPL). It outputs spike probabilities.
|
| Example
parameter file format
|
100.0 Permeability constant A (units per second). 6000.0 Permeability constant B (units per second). 2000.0 Release rate (units per second). 5.05 Replenishment rate (units per second). 2500.0 Loss rate (units per second). 66.31 Reprocessing rate (units per second). 6580.0 Recovery rate (units per second). 1.0 Max. no. of transmitter packets in free pool. 50000.0 Firing rate (spikes per second). |

that the main parameter file was changed to produce this diagram: the
"ANSpikeGen_Simple" module was put in (using the "SpikeGn1.par" module
parameter file, the "Histogm2.par" module parameter file was replaced by
"Histogm4.par" and the number of model runs was set to 200.
