I'm a little confused as to why you wish to use port 1 for this. A synapse is not
aware of incoming or outgoing ports, so if you want to test a particular synapse model,
you can connect it between port 0 of a presynaptic parrot neuron, and port 0 of a
postsynaptic parrot neuron. Could you otherwise please clarify your use case a bit?
With kind regards,

Hi NEST users,
I have a pre- and post-synaptic spike train and I want
to impose these spike trains onto a plastic synapse to see the weight development.
To this end, I thought of having 2
"parrot_neuron_ps" as pre- and post-synaptic neurons connected with the plastic
synapse which uses AMPA receptor.
By doing this, NEST yields the following error:
"NESTError: UnknownReceptorType in Connect_g_g_D_D: Receptor type 1 is not available
in parrot_neuron_ps." which in my case Receptor type 1 is the AMPA receptor.
At the nest documentation about
"parrot_neuron_ps" I found out that I can have the plastic synapse onto port 1
of the postsynaptic parrot neuron
which I hope it will solve the error with the
