A neuron is voltage clamped above threshold and the induced currents are recorded. Then the experiment is repeated: the neuron is voltage clamped to above threshold, and the currents are recorded, but this time the experimenter has applied Tetraethyl ammonium (TEA) to block voltage gated potassium channels. Compared to the first recording (without TEA), which part of the current will change in the second recording?
