Effect of reading on blood flow changes in the posterior cerebral artery in early blind and sighted people - A transcranial Doppler study

摘要

Background: Neuroimaging studies proved that Braille reading resulted in visual cortex activation in blind people, however, very few data are available about the measure of flow increase in these subjects. Therefore, we investigated the flow response in the posterior cerebral artery (PCA) of eleven early blind and ten sighted subjects induced by reading Braille and print, respectively.
