Abstract
The human retina is split vertically at the fovea, with optic fibers from the temporal retina projecting to the occipital lobe on the same side of the head, while nerve fibers from the nasal retina cross at the optic chiasm and project to the occipital lobe of the opposite side. This semidecussation of the optic nerve results in the clinical phenomenon of homonymous hemianopia in cases of optic tract or pathway damage. Semi-decussation might therefore be expected to produce differing visual evoked cortical potentials on the two sides of the scalp. A number of studies have explored this question, with some finding differing VECP’s over the two brain hemispheres.
