Neural network for Braille reading and the speech-reading convergence in the blind: Similarities and differences to visual reading

Gabriela Dziegiel-Fivet et al.

Summary: Research suggests that reading relies on brain areas dedicated to speech processing, with a universal speech-reading convergence phenomenon found among different writing systems. While the neural networks for Braille and visual reading overlap in certain areas, blind individuals do not utilize the speech system for reading like sighted individuals. The engagement of vOT in speech processing and reading in the blind implies its inclusion in a modality-independent language network in the blind.
