The potential reinforcing properties of compounds are an important consideration in the development of CNS-active drugs. Myo-inositol is a marker of glial-neuronal interactions, which are one mechanism of modulation of rewarding properties of addictive compounds. We found that acute administration of nicotine decreased the concentration of myo-inositol and GABA measured with MRS at 7 Tesla in nucleus accumbens in rats. Further investigation of addiction mechanisms and development of biomarkers for drug research is warranted.
