Liu2025 — Lower limb motor imagery EEG dataset for stroke patients (re-hosted from Figshare, BIDS-converted)

Re-hosted EEG data from Liu et al. (2025): Lower limb motor imagery dataset for stroke patients, originally deposited on Figshare under a CC BY 4.0 license. Data has been converted from non-standard BIDS (EEGLAB .set) to proper BIDS format (BrainVision .vhdr/.vmrk/.eeg) using mne_bids.write_raw_bids(). Paper Y. Liu, Z. Gui, D. Yan, Z. Wang, R. Gao, N.
