1. Neurobiological Foundations & Neural Pathways
Hand-eye coordination requires a real-time integration of sensory input and motor feedback. When a target appears on screen, visual signals travel via the optic nerve to the primary visual cortex (V1), which detects the target's spatial coordinates. This information is sent to the posterior parietal cortex, which translates the visual coordinates into a motor map. The prefrontal cortex selects the movement strategy, and the motor cortex initiates the command, sending signals down the spinal cord to move the hand. As the hand moves, the visual system tracks both the cursor and the target, sending real-time feedback to the cerebellum. The cerebellum compares the actual movement path with the intended path, calculating real-time error corrections and adjusting motor signals to ensure the cursor hits the target.
