Yes Peregrinus and TygrHawk
Information is between hemisheres is lost after split brain surgery.
One hemisphere of a patient was falshed a card with the word "bow"; the other hemisphere saw "arrow". Because the patient drew a bow & arrow the assumtion was that the two hemispheres could still communicate. But this was proven to be incorrect when the next test flashed "sky to one hemishere & scrape to the other. Rather than a tall building the patient drew a sky over top of a scraper.

In another test each hemisphere was shown a small picture, one of which was related to a larger picture also presnted to that hamisphere. The patient had to choose the most appropriate picture.
The right hemisphere (the left hand) correctly picked the shovel for the snow storm; the right hand, controlled by the left hemisphere, correctly picked the chicken to go with the birds foot.
Then the person was asked why the left hand (RH) was pointing to the shovel. Because only the left hemisphere retains the abiltiy to talk, it answered. But becuase it could not know why the right hemishere was doing what it was doing, it made up a story about what it could see - namely, the chicken. It said it chose the shovel to clean out the chicken shed.
