[5] The first scientific research study looking at corollary discharge was done by Descartes in 1664 when he published his book the Treatise of Man.
[medical citation needed] In studies done on primate brains, a corollary discharge pathway has been found to begin in the superior colliculus.
A signal is sent back from the occipital lobe to the frontal eye field describing actual visual input.
[3] In summary, the corollary discharge pathway is responsible for helping guide eye movements as well as keeping stable visual perception.
Recent studies suggest that deficiencies within this pathway could be responsible for difficulties that schizophrenic patients have with controlling their own movements.
