NC = Normalised concentration; VOI = volume of interest (F = frontal; RC = right caudate; RAP = right anterior putamen; RPP = right posterior putamen; LC = left caudate; LAP = left anterior putamen; LPP = left posterior putamen; OB = occipital Background; T = Thalamus; M = Midbrain; P = Pons); r = Pearson correlation; Sig. = Significance. Sig. = Significance. Sig of 0.000 represents significance of < 0.001
