stdp_dopamine_synapse and volume_transmitter #433

Open acerebellum opened 7 years ago

acerebellum commented 7 years ago

Is there an possibility to use stdp_dopamine_synapse and volume_transmitter in pyNN, or something similar to that? Thanks....

You could try something like:

import pyNN.nest as sim

vol = sim.Population(1, sim.native_cell_type("volume_transmitter")(deliver_interval=6))
pre = sim.Population(10, sim.IF_cond_exp())
post = sim.Population(5, sim.IF_cond_exp())
mod = sim.Population(1, sim.IF_cond_exp())

syn_type = sim.native_synapse_type("stdp_dopamine_synapse")(vt=int(vol[0]))
connection_mod_vol = sim.connect(mod, vol)
plastic_connections = sim.Projection(pre, post, sim.AllToAllConnector(), syn_type)

(based on http://www.nest-simulator.org/cc/volume_transmitter/). The above code runs with one warning but no errors.

I have no idea if it works as expected - please let us know if you try this and it works.

Of course, this will only run with pyNN.nest. If there is interest in getting this to work with another simulator (e.g. NEURON, Brian2, SpiNNaker) we could add a simulator-independent API for it.
