The Brain As A ‘Task Machine’
The portion of the brain responsible for visual reading doesn't require vision at all, according to a new study published online on February 17 in Current Biology, a Cell Press publication. Brain imaging studies of blind people as they read words in Braille show activity in precisely the same part of the brain that lights up when sighted readers read. The findings challenge the textbook notion that the brain is divided up into regions that are specialized for processing information coming in via one sense or another, the researchers say.
