Mind wandering probes were inserted between trials.       **DATA NEVER PUBLISHED!**       If youre interested in working together, I have 1/3 of the paper already done, including CONSORT diagrams, tables, behavioral analysis, etc.   All EEG data are even fully cleaned and pre-processed.   For CTL and sub-acute mTBI: Session 1 was from 3 to 14 days post-injury and was the only session with MRI. (MRI will be uploaded ...later).  Session 2 was ~2 months (1.5 to 3) and Session 3 was ~4 months (3 to 5) following Session 1.   There was A LOT of subject attrition over timepoints.
