Amphetamine induces Fos-like immunoreactivity in the striatum of primates.
Injections of D-amphetamine (5 mg/kg) three hours before sacrifice were found to elicit robust Fos-like immunoreactivity in the striatum of cynomolgus monkeys and of the common marmoset. Labeled cells were most frequently observed in the medial portion of the caudate nucleus and were distributed in a patchy fashion. Comparison with adjacent sections stained for the calcium binding protein calbindin indicated that the patches of amphetamine induced labeling corresponded to the calbindin-poor striosomes. These results are consistent with those reported in rats and thus suggest similarities in the basic organization of striatal mechanisms underlying the response to amphetamine in rodents and primates.
