parrot_neuron – Neuron that repeats incoming spikes¶
The parrot neuron simply emits one spike for every incoming spike.
An important application is to provide identical poisson spike
trains to a group of neurons. The
poisson_generator sends a different
spike train to each of its target neurons. By connecting one
poisson_generator to a
parrot_neuron and then that
a group of neurons, all target neurons will receive the same poisson
Weights of connections to the
Weights on connections from the
parrot_neuronare handled as usual.
Delays are honored on incoming and outgoing connections.
Only spikes arriving on connections to port 0 will be repeated. Connections onto port 1 will be accepted, but spikes incoming through port 1 will be ignored. This allows setting exact pre- and postsynaptic spike times for STDP protocols by connecting two parrot neurons spiking at desired times by, e.g., a stdp_synapse onto port 1 on the postsynaptic parrot neuron.
