Eye Tracking: An Invaluable and Inexpensive Tool in Neuroscience
Almost all animals with good eyesight exhibit a range of eye movements. These movements allow animals to compensate for shifts in the visual scene and to follow objects that move within that scene. Eye movements have been studied since the early 1900s (Land 2006), and today, eye tracking is a ubiquitous tool used not only in neuroscience but also in other areas such as marketing (Gheorghe, Purcărea, and Gheorghe 2023). It is a common technology applied in virtual and augmented reality devices (Jin et al. 2024).
