Role of orexin receptors in the nucleus accumbens in dopamine-dependent turning behaviour of rats.

abstract：:A neuronal nicotinic acetylcholine receptor (nAChR) subunit, Dalpha4, has been identified and cloned from the fruit fly Drosophila melanogaster, together with several alternatively spliced transcripts. Intron-exon boundaries within the gene encoding Dalpha4 (nAcRalpha-80B) have been identified by comparison of cDNA an...
