iaf_psc_alpha_multisynapse – Leaky integrate-and-fire neuron model with multiple ports

Description

iaf_psc_alpha_multisynapse is a direct extension of iaf_psc_alpha. On the postsynaptic side, there can be arbitrarily many synaptic time constants (iaf_psc_alpha has exactly two: tau_syn_ex and tau_syn_in).

This can be reached by specifying separate receptor ports, each for a different time constant. The port number has to match the respective “receptor_type” in the connectors.

Note

If tau_m is very close to a synaptic time constant, the model will numerically behave as if tau_m is equal to the synaptic time constant, to avoid numerical instabilities.

For implementation details see the IAF_neurons_singularity notebook.
