Electroencephalography (EEG) data plays a crucial role in brain science research as it provides valuable insights into the mechanisms of brain functions. Typical EEG research involves conducting experiments, collecting data, and comprehensive data analysis. The success of such complex studies truly hinges on the collective efforts of multiple researchers. An efficient tool is required to facilitate such collaborative research. While many related tools exist, none specifically aim to enhance efficiency across data management, data analysis, and collaboration. To address this issue, we developed and deployed an integrated cloud-based platform for EEG experiment management, collaboration, and data analysis. Verified by practice, our platform facilitates collaboration, simplifies EEG data analysis for researchers not proficient in programming, and boosts the efficiency of overall EEG research.
