CurrentInjection

inputs.CurrentInjection.CurrentInjection(
    self,
    pre,
    post,
    target,
    name=None,
    copied=False,
)

Inject current from a rate-coded population into a spiking population.

The pre-synaptic population must be be rate-coded, the post-synaptic one must be spiking, both must have the same size and no plasticity is allowed.

For each post-synaptic neuron, the current g_target will be set at each time step to the firing rate r of the pre-synaptic neuron with the same rank.

The projection must be connected with connect_current(), which takes no parameter and does not accept delays. It is equivalent to connect_one_to_one(weights=1).

Example:

inp = ann.Population(100, ann.Neuron(equations="r = sin(t)"))

pop = ann.Population(100, Izhikevich)

proj = ann.CurrentInjection(inp, pop, 'exc')
proj.connect_current()
