iaf_psc_exp_multisynapse – Leaky integrate-and-fire neuron model with multiple ports¶
iaf_psc_exp_multisynapse is a direct extension of iaf_psc_exp.
On the postsynaptic side, there can be arbitrarily many synaptic
time constants (
iaf_psc_exp has exactly two:
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.
tau_m is very close to
tau_syn_in, the model
will numerically behave as if
tau_m is equal to
tau_syn_in, respectively, to avoid numerical instabilities.
For implementation details see the IAF Integration Singularity notebook.
For conversion between postsynaptic potentials (PSPs) and PSCs,

postsynaptic_potential_to_current function in
