Concurrent tDCS with multi-modal MRI - Experiment 1

The provided dataset includes 20 subjects (6 female) with Arterial Transit Time (ATT), water exchange across the BBB (Kw) and cerebral blood flow (CBF)  imaging before (run 1), during (run 2, run 3), and after (run 4, run 5) transcranial direct-current stimulation (tDCS). Subjects were recruited to CUNY IRB standards and provided informed consent on the publication of their data. The three sessions, (ses-1, ses-2, and ses-3), indicate whether subjects were stimulated Sham current (30 sec ramp-up and ramp-down), 2mA anodal tDCS (AF7 - Anode, AF8 - cathode) or 4mA anodal tDCS (AF7,F7 - Anode, AF8, F8 - Cathode), respectively.

Pre-processed files are provided in Nifti (.nii) format with an associated T1w anatomical image. All data has been de-identified to preserve subject anonymity. Data is organized to BIDS standards for ease of processing. It is anticipated that MRI data with concurrent tDCS will benefit the field and allow others to analyze, validate tools, or compare with non-stimulated control measurements.
