[NEST Users] Re: Access weight_recorder data during simulation

Dear Hans, thanks for you suggestions! I am indeed working with plastic synapses, but I am not interested in sharing the values of the weights, I would rather like to trigger a plasticity event based on specific synaptic relations: every time a spike travels through a specific synapse I, I would like to modify the weight of a synapse J in a dynamic way (i.e., in real-time, during the simulation). Thus, I would like to achieve something similar to what a volume transmitter does, except that the event shall be triggered with specific I-J synaptic pairs rather than simply observing a subset of synapses and collecting the spike events within the subset. The `weight_recorder` property I'm interested in replicating is the ability to monitor the sender and target of each spike in the network, and pass that information to my custom synaptic model in NESTML. I hope this makes things a bit easier! Best, Francesco
