+		BIDS-formatted MRI data recorded at the ETH/UZH Animal Imaging Center
+		and first associated with the OPFVTA publication. The data represents
+		f/MRI mouse brain scans with both BOLD and CBV contrasts, using block
+		and phasic stimulation protocols delivered via a laser to the VTA,
+		which is rendered sensitive by channelrhodopsin expression under
+		the dopamine transporter promoter.
