Experiment 1: anatomical landmarks. Location of anatomical landmarks shown on an exemplar brain: cortical landmarks are shown in white (n = 16, 8 each hemisphere): 2 frontal = F1, F2; 2 temporal = T1, T2; insula = In; parietal = Pa; occipital = Oc; cerebellum = Ce. Subcortical landmarks are in yellow (n = 8, 2 midpoint, 3 bilateral): Anterior commissure = AC; frontal horn = FH; occipital horn = OH; 4th ventricle = 4V; putamen = Pu.
