Abstract

d-Amphetamine transiently stimulates the expression of the immediate-early response gene, c-fos, in rat striatal cell nuclei. d-Amphetamine (2.5 mg/kg i.p.) induced a significantly greater expression of Fos-like immunoreactivity in striatum of rats treated three days previously with d-amphetamine compared to rats treated three days previously with saline. This increase in the expression of Fos-like immunoreactivity in rat striatum was characterized by a significantly greater number of immunoreactive nuclei and a significant increase in the intensity of the immunoreactivity. This sensitization of c-fos expression following a repeated administration of d-amphetamine indicates an increased activation of post-synaptic elements in rat striatum.
