inject_currents_into_populations#

inject_currents_into_populations(
populations: Sequence[_Pool],
input_current__AnalogSignal: ]],
) → None[source]#

Injects input currents into the specified populations.

Sets up time-varying current injection using NEURON’s IClamp and Vector.play() mechanisms. This function only sets up the current injection - spike recording and simulation execution must be handled separately by the user.

Parameters:

  • populations (Sequence[_Pool]) – The populations of neurons to inject current into.

  • input_current__AnalogSignal (CURRENT__AnalogSignal) – The analog signal of input currents to inject into the population. Shape should be (time_points, n_pools) where n_pools matches len(populations).

Returns:

Current injection mechanisms are attached to the neurons as side effects.

Return type:

None

Raises:

ValueError – If the number of populations does not match the number of current channels.

Notes

  • Current injection vectors and IClamp objects are stored on each cell as cell._stim_vectors to prevent garbage collection

  • The user is responsible for setting up spike recording and calling h.run()
