Pynn has a release of Triplets STDP?

[Qianhui Liu]

Hi, I wonder if triplets has been included in pynn stdp model. I don't find it in pynn documentation.

Hi,

There are no cross-simulator triplet STDP rules in PyNN.

If you are using PyNN with NEST, you could use the NEST “stdp_triplet_synapse” model:

from pyNN.nest import native_synapse_type, Projection

… create populations ...

synapse_model = native_synapse_type(“stdp_triplet_synapse”)(**parameters)

connections = Projection(pop1, pop2, connector, synapse_type=synapse_model)

If you would like a triplet rule for another simulator (NEURON, Brian, SpiNNaker), please open a ticket in the issue tracker: https://github.com/NeuralEnsemble/PyNN/issues/new

Best regards,

Andrew

Hi Andrew, thanks a lot for your reply. It helps a lot ! 

I now have a following question:

In STDP triplet synapse in nest, there are two parameters "tau_minus" and "tau_minus_triplet", which should be set as properties of postsynaptic neuron. But these neuron properties seem not included in pyNN. So maybe I also need to import native_cell_type. I define a population of if_exp_cond model in pyNN. How can I set the parameter  "tau_minus" and "tau_minus_triplet" ?

Best regards, 

Qianhui
