-PoissonGroup is a [[SpikingGroup]] that implements ''n'' independent homogenous Poisson neurons spiking at a given and generally fixed ''rate''. It is the standard way of adding noise into any network implemented in Auryn. +PoissonGroup is a [[SpikingGroup]] that implements ''n'' independent homogenous Poisson neurons spiking at a given and generally fixed ''rate''.

 **Nota bene**: All PoissonGroups share the same random number generator which is seeded by default the same for each run of a simulation. To create differnt runs it has to be seeded randomly using the ''seed'' function. **Nota bene**: All PoissonGroups share the same random number generator which is seeded by default the same for each run of a simulation.

 To seed the random number generator shared by all [[PoissonGroups]] the function ''seed(int s)'' has to be called. Rate changes can be implemented by calling the method ''set_rate(rate)'' where ''rate'' is given in Hertz. Regular re-setting of the rate will impair the performance of the PoissonGroup. To seed the random number generator shared by all [[PoissonGroups]] the function ''seed(int s)'' has to be called.
