disconnected & communicate! SCIENCE ROCKS

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?"
