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 tau_syn_ex or tau_syn_in, the model
will numerically behave as if tau_m is equal to tau_syn_ex or
tau_syn_in, respectively, to avoid numerical instabilities.
For implementation details see the IAF Integration Singularity notebook.
