Whole-cell patch-clamp recordings of optically evoked EPSC. A, A schematic of the experimental approach. B, An oblique illumination optical image merged with YFP fluorescence (yellow) showing the recording pipette (rec). Scale bar, 100 μm. The inset shows the high magnification image around the recorded neuron (scale bar, 10 μm). CeL, the lateral division of CeA; BLA, basolateral amygdala; LA, lateral amygdala. C. Traces show consecutive fifteen responses (gray) evoked by optical stimulation (duration, 5 ms; every 20-s; blue box) before (left) and during (right) tetrodotoxin (TTX, 1 μM) administration. Red traces indicate the averaged waveforms.
