Transgenic Analyses of Homer2 Function Within Nucleus Accumbens Subregions in the Regulation of Methamphetamine Reward and Reinforcement in Mice.

Initial active hole responding was lower in mice infused with Homer2b-cDNA into the NAC shell than that typically observed under our oral MA operant-conditioning procedures ( Figure 6D ) and the Genotype X Day interaction failed to reach statistical significance [Day effect: F(4,128) = 4.79, p = 0.001; Genotype X Day, p = 0.095].
