Shin2022 (Figshare 20383716) holds the recordings of a closed-loop motor imagery cursor study: 10 healthy participants, one recording day each, moved a cursor toward an instructed right or left target with visual feedback, recorded with a 16-channel dry-electrode g.tec g.Nautilus headset at 250 Hz. The release is organised into live and simulated recordings, each under three experimental conditions (BW, NT and CV), following the authors’ parallel design with a BCI simulator. Released by Hyonyoung Shin, Daniel Suma and Bin He under CC BY 4.0 and described in Frontiers in Human Neuroscience (2022). Only the live human recordings are used here.

Of 110 runs in the release’s human recordings, 9 pairs are byte-identical, leaving 101 distinct runs; 1 incomplete run is held whole. The 100 complete runs hold 2,400 closed feedback windows: 167 end within the first second; of the other 2,233, 13 are constant on at least one channel in their first second, leaving 2,220 signal-valid windows (92.5% of the closed windows), with both targets for all 10 participants. All three arms are scored on them, with participant-bootstrap intervals over 10,000 resamples.
The scores cover the signal-valid windows only: feedback lasting at least one second, and a first second that is finite with positive 1–40 Hz power on all 16 channels. The label is the instructed target in closed-loop cursor recordings, which carry visual, controller and behaviour confounds. The duration control reads the whole feedback duration, known only after the trial ends, so it checks a confound; the spectral arm sits close to it, and no test between arms was run. Ten participants, one recording day each; the intervals are descriptive.
