Neuroscientists propose evolutionary origin of brain's cross-wired motor control

Full article details evolutionary pathway from visual processing to motor control

The published research traces the evolutionary basis for contralateral organization starting with how the eye's lens reverses images on the retina, directing right visual fields to the left brain hemisphere. The article examines the optic tectum (superior colliculus in mammals)—an ancient vertebrate structure present across all vertebrate species—and then explores two conserved sensory pathways (dorsal column and spinothalamic tract) and motor pathways (including the tectospinal pathway) that all cross the body's midline.

“The optic tectum is present in all vertebrate species and, as a result, appears to be among the oldest neuroanatomical structures in vertebrates.”
