1 Recently, a single injection of the typical antipsychotic haloperidol has been shown to increase c-fos expression in the striatum [Dragunow et al. Haloperidol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
2 The present experiments examined some potential neuroanatomical differences in the actions of clozapine and haloperidol by comparing their effects on c-fos expression in the medial prefrontal cortex, nucleus accumbens, striatum and lateral septum. Clozapine Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
3 The present experiments examined some potential neuroanatomical differences in the actions of clozapine and haloperidol by comparing their effects on c-fos expression in the medial prefrontal cortex, nucleus accumbens, striatum and lateral septum. Haloperidol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
4 Haloperidol (0.5, 1 mg/kg) and raclopride (1, 2 mg/kg) produced large increases in the number of Fos-containing neurons in the striatum and nucleus accumbens. Haloperidol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
5 Haloperidol (0.5, 1 mg/kg) and raclopride (1, 2 mg/kg) produced large increases in the number of Fos-containing neurons in the striatum and nucleus accumbens. Raclopride Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
6 Haloperidol, but not raclopride, produced a modest increase in c-fos expression in the lateral septal nucleus. Haloperidol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
7 Clozapine (10, 20 mg/kg) was without effect in the striatum; however, it significantly increased the number of Fos-positive neurons in the nucleus accumbens, medial prefrontal cortex and lateral septal nucleus. Clozapine Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
8 Destruction of mesotelencephalic dopaminergic neurons with 6-hydroxydopamine abolished the increase in Fos expression in the nucleus accumbens and striatum produced by haloperidol and raclopride, and also blocked the clozapine-induced increase in the nucleus accumbens. Oxidopamine Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
9 Destruction of mesotelencephalic dopaminergic neurons with 6-hydroxydopamine abolished the increase in Fos expression in the nucleus accumbens and striatum produced by haloperidol and raclopride, and also blocked the clozapine-induced increase in the nucleus accumbens. Haloperidol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
10 Destruction of mesotelencephalic dopaminergic neurons with 6-hydroxydopamine abolished the increase in Fos expression in the nucleus accumbens and striatum produced by haloperidol and raclopride, and also blocked the clozapine-induced increase in the nucleus accumbens. Raclopride Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
11 Destruction of mesotelencephalic dopaminergic neurons with 6-hydroxydopamine abolished the increase in Fos expression in the nucleus accumbens and striatum produced by haloperidol and raclopride, and also blocked the clozapine-induced increase in the nucleus accumbens. Clozapine Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
12 However, the inductive effects of clozapine and haloperidol on c-fos expression in the lateral septal nucleus and of clozapine in the medial prefrontal cortex were not affected by the 6-hydroxydopamine lesions. Clozapine Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
13 However, the inductive effects of clozapine and haloperidol on c-fos expression in the lateral septal nucleus and of clozapine in the medial prefrontal cortex were not affected by the 6-hydroxydopamine lesions. Haloperidol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
