Dataset of Innovative and Adaptive SSVEP Stimulator Design and Implementation

SSVEP Signal DatabaseOverviewThis database contains SSVEP (Steady-State Visual Evoked Potential) signals recorded from volunteers under different experimental conditions.Recording DetailsExperimental Setup Volunteers: Multiple participantsEnvironments: 4 different recording environments per volunteerChannels: 16 channelsFiltering: Bandpass filter: 1-200 HzNotch filter: 50 Hz Recording Equipment Device: Brain Products V-Amp 16 channelsSoftware: Brain Products Recorder File StructureEach recording session contains three different file formats:1. .eeg FileContains the raw EEG data.2. .amrk FileContains information about the volunteer's focus periods: S2X: Indicates the timestamp when the volunteer started focusing on LED XS3X: Indicates the timestamp when the volunteer stopped focusing on LED X 3. .ahdr FileContains metadata including: Recorded channel informationMultiplier values to be used in data processingRecording date and timeOther header information Included Code FilesMATLAB Scripts (.m files)Two MATLAB scripts are provided: Data loading and preprocessing functionsAnalysis scripts used in this study Arduino Stimulus Code (.ino files)Four different stimulus programs used for hardware control during the experiments.
