To elucidate the mechanism of psychostimulant-induced reverse tolerance [A. Kifune, S.

Ceccatelli, M.J. Villar, M. Goldstein, T. Hokfelt, Expression of c-Fos immunoreactivity in transmitter-characterized neurons after stress, Proc. Natl. Acad. Sci. USA 86 (1989) 9569-9573 [2]; L.

Neurosci. 11 (1991) 2321-2331 [16].] were investigated in mice injected with methamphetamine (2 mg/kg, s.c., one to five times). The ambulatory activity enhanced by either acute or chronic methamphetamine injection was delayed or diminished by lithium chloride (LiCl) pretreatment [R.G. Fessler, R.D. Sturgeon, S.F. London, H.Y. Meltzer, Effects of lithium on behaviour induced by phencyclidine and amphetamine in rats. Psychopharmacology 78 (1982) 373-376 [3].]. How the Li-sensitive c-Fos expression in the dorsolateral geniculate nucleus and striatum is related to methamphetamine-induced behavioral excitation is unclear. This protocol, in combination with c-Fos expression of mouse cerebral regions, may provide a useful tool for quantitation of ambulatory activity during c-Fos expression.
