Correlation matrix of striatal DAT and post-treatment barrier performance

	Post-Tx barriers	Post-Tx 25 cm barrier	Post-Tx 30 cm barrier	NAc DAT	CP Subregion DAT
					dmCP	dlCP	vmCP	vlCP
Post-Tx barriers	1.00			0.25***	ns	ns	ns	ns
Post-Tx 25 cm barrier		1.00	0.61***	ns	ns	ns	ns	ns

Scores are reported as r values showing levels of DAT binding in regions of the CP and NAc and their association with post-treatment performance over barriers

Post-Tx barriers post-treatment performance over all barrier heights, post-Tx 25 cm barrier post-treatment performance over the 25-cm barrier, post-Tx 30 cm barrier post-treatment performance over the 30-cm barrier, DAT dopamine transporter, CP caudate putamen, dmCP dorsomedial caudate putamen, dlCP dorsolateral caudate putamen, vmCP ventromedial caudate putamen, vlCP ventrolateral caudate putamen
