Deaf brain and peripheral vision
A recent study has shown that deaf individuals who experience early and profound hearing loss redistribute their visual brain resources, enhancing the representation of their peripheral visual fields. Rather than increasing overall visual ability, the brain allocates more space to peripheral vision, enabling them to detect movement of objects and events outside the central focus more efficiently—a kind of "danger radar." The study indicates that this neural flexibility explains why some deaf people can monitor their surroundings better despite not hearing sounds. The research involved 16 deaf adults and 16 hearing individuals.
