- •PCA flow velocity increased significantly in blind people during reading Braille.
- •Similar PCA flow increase was evoked by reading alone in blind and sighted subjects.
- •Reading alone induced similar occipital cortex activation in blind and sighted subjects.
- •In sighted people light stimulus evoked higher PCA flow response than reading alone.
- •Light stimulus caused 2/3 of PCA flow increase in sighted people during reading.
