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.}, pages = {97–102--97–102}, title = {Effect of blonanserin on methamphetamine-induced disruption of latent inhibition and c-Fos expression in rats}, volume = {549}, year = {2013}, yomi = {クラマシ, アキ and アベ, ヒロシ and コガネマル, ゴウ and マツオ, ヒサエ and イケダ, テツヤ and エビハラ, コウスケ and フナハシ, ヒデキ and タケダ, リュウイチロウ and ニシモリ, トシカズ and イシダ, ヤスシ} }
