Fig. 4. Effect of etomidate on fast γ-aminobutyric acid type A (GABA^A,fast) inhibitory postsynaptic currents (IPSCs). (  A ) Representative recordings of miniature IPSCs under control conditions (  top traces ) and in the presence of etomidate 0.5 μm (  middle traces ) and 1.0 μm (  bottom traces ). (  B–D ) Analysis of etomidate effects on amplitude (  B ), interevent interval (  C ), and kinetics (  D ) of GABA^A,fastminiature IPSCs (currents normalized to peak current) for the cell illustrated in  panel A.
