NEST HelpDesk | Command Index | NEST Quick Reference

Name:

    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 )

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

Require:

    HAVE_GSL

Receives:

    DataLoggingRequest

Sends:

    SpikeEvent

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.
