Note:  the original thread is about telepathy.

Look up "Sperry split brain" in www.google.com.  People with
the corpus callosum cut have the direct connection between the
hemispheres severed.  This is the "split brain".  Many studies
indicate that after such surgery, each hemisphere can be provided
with different information, and that the information in fact is not
shared between them even though there are other pathways
that remain intact.

The application to telepathy is offered in the spirit originally
intended, as a somewhat humorous thought.  Certainly not
a definitive proof against telepathy.

But unless you show convincing hard experimental evidence based
on carefully controlled studies and published in reputable refereed
journals FOR telepathy, I think you had better at least drop
bionet.neuroscience from your list of news groups.
