  • Data shown are the mean ± SEM of cerebellar membranes prepared independently from six animals. Saturation analysis used eight concentrations of ligand in duplicate for each animal.Bmax (fmol/mg protein) andKd (nm) values were determined by nonlinear least-squares fit of the saturation curves using the data analysis software RS1.

  • * Significantly different from +/+ (p < 0.05);

  • F1-160 significantly different from +/+ (p < 0.005). DS, Diazepam sensitive.
