inhomogeneous_poisson_generator – Provides Poisson spike trains at a piecewise constant rate ============================================================================================ Description +++++++++++ The inhomogeneous Poisson generator provides Poisson spike trains at a piecewise constant rate to the connected node(s). The rate of the process is changed at the specified times. The unit of the instantaneous rate is spikes/s. By default, each target of the generator will receive a different spike train. .. include:: ../models/stimulation_device.rst rate_times Times at which rate changes (list of ms) rate_values Rate of Poisson spike train (list of spikes/s) allow_offgrid_times If false, spike times will be rounded to the nearest step if they are less than tic/2 from the step, otherwise NEST reports an error. If true, spike times are rounded to the nearest step if within tic/2 from the step, otherwise they are rounded up to the *end* of the step. Default: false Set parameters from a stimulation backend ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The parameters in this stimulation device can be updated with input coming from a stimulation backend. The data structure used for the update holds one value for each of the parameters mentioned above. The indexing is as follows: 0. rate_times 1. rate_values Receives ++++++++ DataLoggingRequest Sends +++++ SpikeEvent See also ++++++++ :doc:`Device `, :doc:`Generator `
