by Cristiano Alessandro 16 Feb '21

16 Feb '21

Hi all, I am writing a new neuron model using nestml and then I modify the C++ code. I am having a hard time defining an input parameter of the neuron as an array of numbers. Is this even possible? Thanks. Regards Cristiano

Master branch Doxygen location
by Itaru Kitayama 08 Feb '21

Hi, The NEST "Read the Docs" tells us how to invoke doxygen, but I am wondering if the community continuously builds Doxygen db every time a series is committed to master and put it somewhere.

Spike Event Multiplicity
by Benedikt Feldotto 04 Feb '21

04 Feb '21

Dear all, I realized that spikes that pass synapses (e.g. stdp_connection) are not processing a "multiplicity" value. However, some other nodes e.g. spikes delivered from the volume_transmitter into the stdp_dopa_connection include such a value. Does this mean, the multiplicity for spike events that pass a synapse is always equal to 1? Thanks! Best Regards, Benedikt -- Benedikt Feldotto M.Sc.
