Acute administration of typical and atypical antipsychotics has been reported to induce regionally distinct patterns of c-Fos expression in the rat forebrain. Furthermore, atypical index, the difference in the extent of increased Fos-like immunoreactivity (Fos-LI) in the nucleus accumbens (NAc) shell versus the dorsolateral striatum (DLSt), has been(More)
RATIONALE Antidepressants preferentially facilitating serotonin seem to be particularly effective for treating the anxiety and aggressive component of the depressive syndrome, whereas those with a noradrenergic profile seem to be more effective in reducing psychomotor retardation, although their overall antidepressant effects are about the same. However,(More)
There are many studies of the mechanisms of antidepressants; however, most of these studies were conducted on the hippocampus or frontal cortex. In the present study, we hypothesized that the nucleus accumbens and caudate/putamen might be major targets for antidepressant effects. Thus, we focused on G(olf) protein, a stimulant alpha-subunit of G protein(More)
INTRODUCTION Recently, second-generation antipsychotics (SGAs) have been widely used in the treatment of mood disorders. However, the mechanisms of the antidepressant effect of SGAs remain unclear. We proposed that Golf protein, a stimulant alpha-subunit of G protein coupled with the dopamine D1 receptor, might a play the key role in the antidepressive(More)
