sinusoidal_gamma_generator – Generates sinusoidally modulated gamma spike trains¶
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
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.
