Outline of Final Research Achievements |
In this study, we examined the effects of nicotine on reward-based decision-making in healthy and methamphetamine (METH)-treated rat. We analyzed the performance of rats in a gambling test for rodents. Nicotine treatment (0.3 mg/kg) ameliorated the abnormal arm-choice behavior of METH-treated rats in the gambling test. However, chronic nicotine treatment (0.3 or 0.6 mg/kg) did not show changes in arm-choice behavior in healthy rats. Our findings suggest that nicotine may have some therapeutic effects against impairment of decision-making in METH addicts.
