Humans Can Learn Echolocation in 10 Weeks, Reshaping the Brain

New studies show that both blind and sighted adults can learn click-based echolocation after 10 weeks of training, with brain scans revealing functional and structural changes in the primary visual (V1) and auditory (A1) cortices. The findings indicate adult brain plasticity for sensory repurposing beyond vision, suggesting the brain can adapt to process echoes; related animal research hints at species-specific neural adaptations in echolocation.
