Figure 7

Factor 1 in hippocampus was composed of NAA, NAA + NAAG,Glu,Glu + Gln; Factor 2: PCr, Ins, and Tau; Factor 3: Gln, GPC + PCh. In PFC, Factor 1 was composed of: NAA, GPC + PCh, NAA + NAAG, Cr + PCr; Factor 2: Ins and Tau; Factor 3: Glu, Glu + Gln (AFR = animal facility rearing; EE = environmental enrichment; VEH = vehicle; JWH = JWH-018).
