Caudate nucleus, putamen, globus pallidus, and nucleus accumbens volumes were extracted from whole-brain segmentation images. Participants were scanned at three time points: prior to ECT (baseline, t0), one week after (t1), and six months after ECT completion (t2). The volumetric data were normalized to account for differences in total brain volume using a standard approach (Jack et al.48).
