Dear Guilherme,

as this indeed looks like a bug in NEST, we will continue the discussion on the NEST issue tracker at https://github.com/nest/nest-simulator/issues/1242. Thanks for bringing this to our attention.

Best regards, Jochen!

Hi everyone,

I'm getting strangely different results if I use stdp_dopamine_synapse with more than 1 local thread. For instance, the mini-code bellow creates a connection with an initial non-zero DA concentration and at t=1000 ms a spike arrives at the volume transmitter. If I run it with one thread I get an initial decay on the DA concentration and then a bump at t=1000 ms. Which is the expected behavior. But if I run the same thing with 2 threads, then I get just the decay. As if the spike hasn't arrived at the volume transmitter. Is this the expected behavior or is it maybe a bug?

Best, Gui
