Arachidonic acid and estimated binding potentials are In-transformed. Data from separate brain regions and their corresponding regression lines are displayed in different colors as shown in the legend. Independent variables are estimated binding potentials: A) BPP = (VT − VND) B) BPND (VT − VND)/VND
C) BPF (VT − VND)/fP. Abbreviations: acn, anterior cingulate; amy, amygdala; dpu, dorsal putamen; hip, hippocampus; mid, midbrain; tha, thalamus.
