parrot_neuron – Neuron that repeats incoming spikes
Description
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 parrot_neuron
to
a group of neurons, all target neurons will receive the same poisson
spike train.
Remarks
Weights of connections to the
parrot_neuron
are ignored.Weights on connections from the
parrot_neuron
are handled as usual.Delays are honored on incoming and outgoing connections.
Only spikes arriving on connections to port (receptor
) 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 onto port 1 on the postsynaptic parrot neuron.
