Radiotracer uptake in the whole brain. Whole brain uptake of [11C]SNAP-7941 before and after displacement with either vehicle (a) or 15 mg/kg (±)-SNAP-7941 (b) and [18F]FE@SNAP before and after displacement with either vehicle (c) or 15 mg/kg (±)-SNAP-7941 (d). Data are displayed as mean ± SEM from independent experiments (n ≥ 3). Differences among groups were tested using a two-tailed parametric paired t-test (ns = P > 0.05; **P < 0.01). If not visible, error bars are within the margin of the symbols.
