WM Working Models www.iModel.org/wm
OverviewThis 1D model implements a linear filter followed by spike train generation. It also may contain any number of units in a second layer, defined by <unit> objects, that combine the spikes from the linear unit with independently generated Poisson spikes.
Configuring the Model
ParametersThese parameters set the basic simulation settings:
- tscale - temporal resolution (samples per second)
- tn - duration of the model (sampling units)
Filterslin_01 models include a 1-D <filter> object that specifies parameters for the temporal filter.
Spike Generationlin_01 models require a <spike_gen> object that defines the method of spike generation from the final filter output.
Unitslin_01 models may optionally include <unit> object specifying parameters for 2nd layer units.
Model ComponentsThe following command allows users to output the temporal filter itself:
- write_dog_temporal [outfile] - write the temporal filters. This includes the temporal kernel and the Gaussian mask, which multiplies the biphasic kernel to adjust the size of the positive and negative lobes.
Model ResponsesThe following response types can be requested:
A template .rsp file including these quantities can be downloaded here.
- spikes - spike times
- f - linear filter output
- prob - probability of spiking (if Poisson spike generation)
