chr@chymera.eu Horea Christian sci@gentoo.org Gentoo Science Project 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.
