Brain Can Learn Echolocation in 10 Weeks, New Study Finds

A 10‑week program trained 12 blind and 14 sighted adults in echolocation techniques, with neuroimaging showing increased activity in the primary visual and auditory cortices. The study demonstrates that the adult brain can rewire to interpret echoes for spatial awareness, with experts achieving centimeter‑level precision, suggesting echolocation training could become a mainstream tool for vision impairment.
