Losing the ability to read

For those
of you who have access to the New Yorker, there is a
great article by Oliver Sacks on people who have lost
the ability to read after a stroke. They can still
write, but they cannot go back and read their own
writing. I wish the entire piece was available
online, but there is an abstract, and hopefully if
you are interested, you can chase it down at the
library. It's subscription only for the full article.
(So really, subscribe to the New Yorker, what else
can I say? So many good articles in it.) But back to
this one: It's fascinating, as is much of what Oliver
Sacks writes:
Whatever language a person is reading, the same area of inferotemporal cortex, the visual word form area, is activated. Why should all human beings have this built-in facility for reading when writing is a relatively recent cultural invention? ... Writing, a cultural tool, has evolved to make use of the inferotemporal neurons’ preference for certain shapes. The origin of writing and reading cannot be understood as a direct evolutionary adaptation. It is dependent on the plasticity of the brain, and on the fact that experience is as powerful an agent of change as natural selection. We are literate not by virtue of a divine intervention but through a cultural invention and a cultural selection that make a creative new use of a preëxisting neural proclivity.
Harold Engel, the patient who presented himself to Sacks after losing his ability to read, had been a novelist, and wrote mysteries. The story of how he worked to start writing again, without being able to edit or revise his drafts directly, is amazing - dictation and audio recordings and having someone read his drafts to him had to take the place of him being able to reread what he had written.
