‘Unprecedented’ eye-tracking could reveal hidden memory in Alzheimer’s patients: Study

Eye-tracking technology is revolutionizing memory assessment by detecting memories patients cannot verbally express. Tel Aviv University researchers found that eye movements can reveal stored memories even when individuals can't consciously recall them. In their study, participants' eyes automatically shifted to anticipate surprises during second viewings of videos, even when they couldn't verbally recall the content. This breakthrough could transform memory assessment for non-verbal individuals, including infants, brain injury patients, and those with advanced Alzheimer's, using simple technology like laptop or smartphone cameras.
