Learned aversion and rearing movement in rats given LiCl, PbCl2 or NaCl.

The effects of an i.p. injection of 0.15 M LiCl resembled closely the effects of another toxic substance, 0.005 M PbCl2, on conditioned aversion to saccharin and rearing movements in male rats. The findings suggest that nonspecific aversive after-effects of a LiCl injection can account fully for prompt effects of LiCl on rearing behavior.
