A three-class motor imagery EEG dataset (left hand, right hand, feet) from the MI-A track of the 2023 World Robot Contest BCI competition. It includes recordings from nine participants, two of whom are stroke patients, with 90 cued 4-second imagery trials each (30 per class). Data were acquired at 1000 Hz from 59 EEG channels using a Neuracle wireless system and re-released in BIDS format with HED annotations via MOABB.

The BETA database contains 64-channel EEG recordings from 70 healthy participants (aged 9-64 years) performing a 40-target cued-spelling SSVEP-BCI task. Stimuli used joint frequency and phase modulation (JFPM) on a 5x8 virtual keyboard, with frequencies of 8-15.8 Hz. Data were recorded in a normal classroom rather than a shielded room, giving a more realistic benchmark for SSVEP-based brain-computer interfaces.

This dataset contains 32-channel EEG recordings from 8 healthy participants performing a combined steady-state visual evoked potential (SSVEP) brain-computer interface task. Spatially overlapping arrow stimuli at a single location, flickering at distinct frequencies derived from an 85 Hz CRT refresh rate, encode four directions (up, down, left, right). Participants covertly attended to one direction per trial, and the data cover three stimulation and attention schemes across two experiments.
