					Putamen
	Nucleus accumbens		Caudate		Ventral		Dorsal		Orbitofrontal
Subject	Affected side	Unaffected side	Affected side	Unaffected side	Affected side	Unaffected side	Affected side	Unaffected side	Affected side	Unaffected side
Healthy control (n = 8)	2.08 ± 0.20		2.23 ± 0.24		2.36 ± 0.29		2.51 ± 0.33		0.25 ± 0.08
PD patient (n = 12)	1.29 ± 0.30	1.42 ± 0.25	1.48 ± 0.38	1.75 ± 0.30	1.18 ± 0.36	1.43 ± 0.37	0.99 ± 0.35	1.40 ± 0.47	0.17 ± 0.04	0.18 ± 0.06
% reduction	38%	32%	34%	22%	50%	39%	61%	45%	34%	28%

Each value is expressed as ratio index. % reduction denotes level of change in ratio index of PD patient compared with healthy control.
