The visual system is a complex network of structures and processes within the brain that allows organisms to receive, interpret, and respond to visual stimuli from the environment. This system includes the eyes, optic nerves, and various regions of the brain responsible for processing visual information. Research in the visual system aims to understand how visual information is processed and interpreted, how visual perception contributes to behavior and cognition, and the mechanisms underlying visual disorders and impairments. It also investigates how the brain adapts to changes in visual input, such as during development, aging, or following injury. Studies in this area may use a variety of techniques, including neuroimaging, electrophysiology, psychophysics, and computational modeling, to investigate the structure and function of the visual system at different levels of analysis. Overall, research in the visual system is crucial for understanding how we perceive and interact with the world around us.
