Before revision:  As an input-output approach, I-V curve shaping proves effective in enabling robust and accurate control of the circuit behavior , suggesting a close analogy to the biophysical mechanisms of neuromodulation  .
After revision:  As an input-output approach, I-V curves) of the circuit in prescribed timescales. In turn, shaping those I-V curves determines the excitability properties of the circuit. We show that this methodology enables both robust and accurate control of the circuit behavior , suggesting a close analogy to the biophysical mechanisms of neuromodulation .
