Studies on the flower colors in the camellia the anthocyanin constitution in camellia reticulata camellia saluenensis camellia pitardii camellia hongkongensis camellia rosaeflora and camellia maliflora and in the cultivars derived from interspecific hybridization

Our results suggest that neurotensin input in the ventral tegmental area during initial methamphetamine exposure contributes to the acquisition of methamphetamine self-administration and modulates later intake and methamphetamine-seeking behavior in mice. Furthermore, our results highlight the role of endogenous neurotensin in the ventral tegmental area in the reinforcing efficacy of methamphetamine, independent of its psychomotor effects.
