parrot_neuron_ps

Command: parrot_neuron_ps


Sends
SpikeEvent

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 on connection 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 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 post-synaptic 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 post-synaptic parrot neuron.

Please note that this node is capable of sending precise spike times
to target nodes (on-grid spike time plus offset). If this node is
connected to a spike_detector the property "precise_times" of the
spike_detector has to be set to true in order to record the offsets
in addition to the on-grid spike times.
