  "summary": "Within the field of electrophysiology, I-V curves are a primary experimental means of characterizing ion channel behavior. By directly measuring ionic currents across membranes, electrophysiological techniques quantify key properties, including conductance, ion selectivity, and voltage dependence. We demonstrate a method of linking experimentally observed ion flux with microscopic mechanistic…",
