To examine the functional state of striatal neurons in response to D1 receptor activation, AC5^+/+ and AC5^-/- mice are injected with the D1 agonist (+)-Dihydrexidine (30 mg/kg, i.p.) and obtained the dorso-lateral striatum and NAc, separately, 45 min later for RT-PCR analysis. These experiments reveal that (+)-Dihydrexidine -triggered induction of the immediate early genes, c-fos, egr-1, and junB, in the NAc is markedly enhanced in AC5^-/- mice compared with that in AC5^+/+ mice, while the induction in the dorso-lateral striatum is suppressed in AC5^-/- mice^[3].
