***CrowdsSourced*** consists of EEG data collected as part of a study investigating brain activity during a resting state task, which included two conditions: *eyes open* and *eyes closed*, each lasting 2 minutes. The dataset contains EEG recordings from 60 participants, but only 13 successfully completed both conditions. The recordings were captured using 14-channel EEG headsets—specifically the *Emotiv EPOC+*, *EPOC X*, and *EPOC* devices. These devices provide high-quality, wireless brainwave data that is ideal for analyzing resting-state brain activity [1]. |

The data was initially recorded at a high frequency of 2048 Hz and later downsampled to 128 Hz for processing. To segment the data for analysis, we used a 2-second window (equivalent to 256 time steps) with a 32 time-step stride to capture the dynamics of brain activity while maintaining a manageable data size. The raw EEG data for the 13 participants, along with preprocessing steps, analysis scripts, and visualization tools, are openly available on the Open Science Framework [2]. This version of the dataset has been split into cross-validation folds based on participant. |
