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
Please note that weights of connections to the
are ignored, while weights on connections from the
to the target are handled as usual. Delays are honored on both
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, for example, a
stdp_synapse onto port 1 on the postsynaptic parrot neuron.
