Hi Ady,
in NEST 3 allowing autapses is a property of the connection, not of the kernel anymore. So
you give it in the 'conn_spec' dictionary of the Connect() call:
Autapse
An /autapse/ is a synapse (connection) from a node onto itself. Autapses are permitted
by default, but can be disabled by adding |'allow_autapses': False| to the
connection dictionary.

Same holds true for multapses.
Let us know if that works for you.
Best regards,
Dennis

Hi all,
Is there a way to allow/disallow autapses and multapses for structurally plastic
synapses in NESTv 3.1?
I used the following code for disabling autapses in NESTv2.20.1 with:
nest.SetKernelStatus({
'structural_plasticity_synapses': {
'syn1': {
'model': 'copied_synapse_model',
'post_synaptic_element': 'Den_exc',
'pre_synaptic_element': 'Axon_exc',
}
},
'autapses': False,
})
However, this does not work in NEST 3.1 (Error: "`autapses` is not a valid
kernel parameter, valid parameters are: ...")
I am moving to NEST 3.1 and would like to disable autapses for structurally
plastic neurons (i.e., no direct connections between synaptic elements of the
same neuron).
Thanks for any help :)
Best regards,
Ady

Dear Aadhar,
Unfortunately, there is no way to disable autapses with structural
plasticity at the moment in NEST 3. The only work around currently
available, which is only valid if you are not connecting one population
with itself but only to other populations, would be to not grow the pre
and post synaptic elements in the same neurons.
I have added an issue in the github repository of nest
(https://github.com/nest/nest-simulator/issues/2212) to follow up on
your question.
All the best,
Sandra
