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
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 receptor.
