The right hemisphere presents the world with detail and depth, while the left represents it abstractly, undetailed and even in one plane
The right hemisphere allows for the sense of spatial depth, whereas the left understands depth categorically, i.e. above, below. The right hemisphere tends to present the world realistically, with visual detail and in three dimensions, with depth; and an aesthetic sense of the intensity and beauty of visual representations comes largely from the right hemisphere. The right hemisphere represents objects as having volume and depth in space, as they are experienced; the left hemisphere tends to represent the visual world schematically, abstractly, geometrically, with a lack of realistic detail, and even in one plane. Drawings of buildings, in individuals with an inactivated right hemisphere, may even be laid out flat with all facades simultaneously visible, as in a child’s drawing. A patient studied by Micheal Gazzaniga and Joseph LeDoux, who underwent a commissurotomy, could draw a cube normally with either hand prior to the operation, but following the procedure could draw only a poor diagram with his favored right hand, though the left hand was able to draw a 3-dimensional construct of a cube.
