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

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

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.

Parameters¶

The following parameters can be set in the status dictionary:

rate	spikes/s	Mean firing rate, default: 0 spikes/s
amplitude	spikes/s	Firing rate modulation amplitude, default: 0 s^-1
frequency	Hz	Modulation frequency, default: 0 Hz
phase	real	Modulation phase in degree [0-360], default: 0
order	real	Gamma order (>= 1), default: 1
individual_spike_trains	boolean	See note below, default: true
