sinusoidal_gamma_generator

Command: sinusoidal_gamma_generator


Description

sinusoidal_gamma_generator generates sinusoidally modulated gamma spike trains. By default
each target of the generator will receive a different spike train.

The instantaneous rate of the process is given by

f(t) = rate + amplitude sin ( 2 pi frequency t + phase * pi/180 )

Parameters

The following parameters can be set in the status dictionary:

rate double - Mean firing rate in spikes/second default: 0 s^-1
amplitude double - Firing rate modulation amplitude in spikes/second default: 0 s^-1
frequency double - Modulation frequency in Hz default: 0 Hz
phase double - Modulation phase in degree [0-360] default: 0
order double - Gamma order (>= 1) default: 1

individual_spike_trains bool - See note below default: true

Remarks

- The gamma generator requires 0 <= amplitude <= rate.
- The state of the generator is reset on calibration.
- The generator does not support precise spike timing.
- You can use the multimeter to sample the rate of the generator.
- The generator will create different trains if run at different
temporal resolutions.

- Individual spike trains vs single spike train:
By default the generator sends a different spike train to each of its targets.
If /individual_spike_trains is set to false using either SetDefaults or CopyModel
before a generator node is created the generator will send the same spike train
to all of its targets.
