Current–voltage (IV) curves. IV curve measured after the administration of 10 µM GABA (black squares) and after uncaging 10 µM RuBi–GABA with 1PE (458 nm, 100 ms, 9 µW-red circles). Current peak values (average of data recorded for at least four cells) are normalized to the current peak recorded for − 60 mV.
