Abstract: Several CART (cocaine- and amphetamine-regulated transcript) peptides have been identified in the brain. One peptide, rlCART 55-102, has been previously characterized in locomotor and feeding assays in rodents. The present study characterized the locomotor-stimulating effect of several additional CART peptides after intra-VTA administration in rats. The results confirm earlier findings that intra-VTA administration of rlCART 55-102 dose-dependently increased locomotor activity. Intra-VTA administration of rlCART 62-102 increased activity compar...
