Abstract

Not All Mice Are Equal Different laboratories often use different strains of inbred animals, but one cannot make behavioral comparisons and assume that their reaction to interventions will necessarily be similar. Kumar et al. (p. 1508 ) have detected differences in cocaine response between the widely used C57BL/6N and C57BL/6J mouse strains and used quantitative trait locus analysis to identify a mutation in an inducible gene, Cyfip , that interacts with the Fragile X protein (FMRP) to regulate sensitivity and sensitization to cocaine through regulation of neuronal connectivity.
