PBS is showing an episode of the series "Curious." It is about the brain.
Title: Mind Brain Machine
In one segment they talk about people who grew up without a corpus calosum.
This is the part of the brain that links the hemispheres of the brain.
I had previously seen shows about people who had their corpus calosum cut in
adult life. The folk in this show never had one.
While these folk are clearly not schizophrenic, they seem to have some of
the negative symptoms of Sz. Also, they have social interaction difficulty,
which *some* scheezers have.
I found all this intensely interesting, but I'm not sure what to conclude
about it.
Wild guess: -that the onset of schizophrenia, in part, impairs the function
of the corpus calosum.
