With current master it is possible to use the index of the neuron in a mathematical
expression when specifying the rate (see our documentation on
It is currently not possible to include the current time `t` however.
Using parametrization to get the rate to depend on the global id is not straight forward
however, because you will need to create one poisson generator per neuron, each with a
rate depending on the individual neuron. Another problem is that nest.poisson_generator
does not accept negative rates. And, as it is not possible to use the current time, you
would be better off creating a new poisson model where you can define your rate. The best
way to do so it to use NESTML (https://nestml.readthedocs.io/en/latest/
). Both the index
id and current time should be available on this level. I have added our NESTML expert

Emne: [NEST Users] spatiotemporal Poisson generator
Is it possible to include a spatiotemporal poisson generator in the simulation?
I am trying to apply a current to a population of neurons which is something like this?
where `i` is the index of the neuron and `t` is the current time of the simulation.
Thank you for any guidance.
