When trying to map out how<unk><unk>  works in the brain, it is important to begin with the superior colliculus. It is responsible for receiving visual signals from the retina. In studies done on primate brains, a<unk><unk>  pathway has been found to begin in the superior colliculus. After receiving current information about the visual field, a<unk><unk>  signal is sent from the superior colliculus to the frontal eye field, via the medial dorsal nucleus of the thalamus. The frontal eye field plays a very important role when it comes to eye movements. Particularly the frontal eye field is responsible for much of the saccadic eye movements that eyes make. Once the frontal eye field is activated by the<unk><unk>  signal, it sends a predictive signal to the occipital lobe. This signal essentially predicts what the visual field should look like after an eye movement. A signal is sent back from the occipital lobe to the frontal eye field describing actual visual input. In summary, the<unk><unk>  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.
