Fig. 2. The lack of effect of racemic thiopental on the fast and slow components of the excitatory postsynaptic currents derived from biexponential fits. (A ) Amplitudes of the fast (open circles) and slow (filled circles) components, normalized such that the sum of the fast and slow components is equal to unity in the absence of anesthetic. (B ) Fast (open circles) and slow (filled circles) time constants. (C ) Charge transfer for the fast (open circles) and slow (filled circles) components, normalized such that the total charge transfer for the control equals unity. The points represent mean values (for an average of 22 cells). In all cases the lines are drawn by eye and have no theoretical significance.
