EEG raw data from a flickering checkerboard stimulation

Database composed of 8 participants (aged between 21 and 44 years) EEG datasets. Stimuli presented dich-optically (60 Hz refresh rate and 1920x1080 pixel resolution). Monochromatic visual stimulation, alternating between two patterns: off and on. Off - presentation of a homogeneous gray screen (luminance set at half of its dynamic range). On - checkerboard inverting at 20 Hz, superimposed on a gray homogeneous background. The files are *.mat datasets with raw EEG signal (1000 Hz sampling rate). Each trial comprehends a stimulation sequence of approximately 3 minutes.
