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

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
