| 内容記述 | To clarify the psychopharmacological profile of blonanserin, a novel antipsychotic, we examined its effect on the methamphetamine-induced disruption of latent inhibition （LI） and the neural activation related to this effect in rats. To evaluate the LI, we used a conditioned emotional response in which a tone （conditioned stimulus） was paired with a mild foot shock （unconditioned stimulus）. This paradigm was presented to rats licking water. Methamphetamine-induced （1.0 mg/kg, i.p.） disruption of LI was significantly improved by the administration of a higher dose （3.0 mg/kg, i.p.） of blonanserin and tended to be improved by 1.0-mg/kg blonanserin and 0.2-mg/kg haloperidol but not by a lower dose （0.3 mg/kg） of blonanserin. Immunohistochemical examination showed blonanserin （3.0 mg/kg, i.p.） increased c-Fos expression in the shell area but not in the core area of the nucleus accumbens while methamphetamine （3.0 mg/kg, i.p.） produced the opposite expression pattern. Blonanserin also increased the number of c-Fos expressions in the central amygdala nucleus but not in the basolateral amygdala nucleus or the prefrontal cortex. Blonanserin ameliorates the methamphetamine-induced disruption of LI, as other antipsychotics do, and a neuronal activation and/or modulation of neurotransmission in the nucleus accumbens is related to the disruption of LI by methamphetamine and to its amelioration by blonanserin. | |||||||||||||||||||||||
