Quality of description of concentration–response data with different assumed values for L_WT and N_GABA. The mean squared differences (MSD) between the predicted and measured concentration–response data are shown for different values of L_WT and N_GABA. The concentration–response data (see Fig. 3B) were fit with various values for N_GABA as indicated on the abscissa and three values for L_WT (9000 ♦, 27,000 □, and 3000 +). An F test on the ratio of MSD values indicated that the difference between N_GABA = 2 and N_GABA = 4 or 5 was marginally statistically significant (P < 0.04 for all L values, uncorrected for multiple comparisons).
