Initial magnitude (A) and extinction (B) of CTA expressed as saccharin preference during 2-bottle tests in rats after repeated injections of NaCl or LiCl (0.15 M, 12 ml/kg, i.p.) at 48-h intervals. NNN rats received 2 injections of NaCl, and a third injection of NaCl paired with saccharin. NNL rats received 2 injections of NaCl, and a third injection of LiCl paired with saccharin. LLL rats received 2 injections of LiCl, and a third injection of LiCl paired with saccharin. NNN rats showed a consistently high preference for saccharin. Both NNL and LLL groups showed a robust initial CTA to saccharin with slow and incomplete extinction over 19 days. * p < 0.05 vs. NNN.
