Recent data suggests that galanin - a neuropeptide - attenuates the rewarding effects of cocaine. For one, knock out mice deficient in galanin show increased cocaine- conditioned place preference. In addition preliminary data collected in our lab suggests that galnon attenuates cocaine self-administration. This study aimed to further investigate the role of galanin in cocaine reward utilizing two different paradigms: locomotor activity and self-administration. The results suggest that galanin knock-out mice are more sensitive to the rewarding effects of cocaine. Galanin knock-out mice treated with 10 mg/kg cocaine intraperitoneally (IP) were found to be significantly more active than their wild-type counterparts. In addition, although nothing statically sound can be said about the effect of the genotype on the number of infusions in the self-administration experiments, the single galanin knock-out mouse that did acquire self-administration self-administered more at each level of cocaine.
