My study looked at neural activity during different types of visual depth perception in 8 subjects using an EEG, mainly focusing on how we perceive depth in real life. There are two different types of visual depth - pictorial depth (depth on a two-dimensional plane, induced by pictorial depth cues such as shading) and stereo depth (true three dimensional depth believed to be induced by binocular disparity). In real life, pictorial depth cues and binocular disparity are both present in our daily experiences, which leads to the simultaneous perception of stereo and pictorial depth.
