ScienceDaily (Oct. 19, 2011) — Like a bridge
that spans a river to connect two major metropolises, the corpus
callosum is the main conduit for information flowing between the left
and right hemispheres of our brains. Now, neuroscientists at the
California Institute of Technology (Caltech) have found that people who
are born without that link -- a condition called agenesis of the corpus
callosum, or AgCC -- still show remarkably normal communication across
the gap between the two halves of their brains.
This was a real surprise," says Tyszka. "We expected to see a lot less
coupling between the left and right brain in this group -- after all,
they are missing about 200 million connections that would normally be
there. How do they manage to have normal communication between the left
and right sides of the brain without the corpus callosum?"
