Brain responses to 2D versus 3D images using EEG

Brief description

This dataset contains EEG signals of 11 test subjects. The EEG signals were recorded from 32 channel scalp electrodes following the international 10-20 system. The subjects were aged between 20 and 53 years old. 2 out of 11 were female, and all had perfect or corrected to perfect (in the case of 4 participants) eyesight. One set of test results was rejected due to poor EEG cap connection quality resulting in unusable EEG readings. In each session, 400 visual stimuli were presented where a cube was used as the non-target (80%) while a sphere was used as the target (20%). Each stimulus lasted for 100 ms, followed by one second of black screen. Subjects were asked to press a key whenever a target stimulus is spotted. Each subject was tested over six sessions on the same day where in each session, the test were carried out at three levels of occlusion (0%, 30% and 70% occlusion) for both 2D and 3D visualization.
