WebThe general function of the tectal system is to direct behavioral responses toward specific points in body-centered space. Each layer contains a topographic map of the surrounding world in retinotopic coordinates, and activation of neurons at a particular point in the map evokes a response directed toward the corresponding point in space. WebJul 8, 2024 · It produces gaze shifts initiated by the direction of the eye movement. It will create a head shift or turn while the eyes counter-rotate to stabilize. Superior colliculus structures assist with neck movement by sending signals to the muscles to turn and respond to visual stimuli. It works with oculomotor and head pathways.
