Figure 2.
Spontaneous bioelectric activity of hippocampal neurons with or without IFN-γ treatment. (A) Spontaneous firing of action potentials persisting over at least 10 min by an untreated neuron (upper trace). Additional suprathreshold current pulses elicited single action potentials (lower trace, left). Depolarising ramps demonstrated sodium and potassium currents, downward and upward deflections, respectively (lower trace, right). (B) Hippocampal neuron treated with IFN-γ (100 U/ml) for 3 d.
