Sperry was awarded this prestigious award for his work with "split-brain" patients.

Such "split-brain" patients appear, superficially, entirely normal after the surgery.

In human split-brain patients, it is quite clear that fairly elaborate logical analysis can proceed surrounded by verbal incompetence.

In split-brain patients it has been shown that the left hemisphere retains language function, the right does not.

Disconnection studies in split-brain patients supported this conclusion, showing that the left hemisphere is sufficient for language.

Studies on split-brain patients have dominated Dr. Gazzaniga's work ever since.

Strong support for this hypothesis comes from studies of split-brain patients who use the right hemisphere for reading.

After thousands of experiments carried out on normal subjects and split-brain patients, scientists still passionately disagree.

More recently, however, interest in the left and right brain is due to work involving split-brain patients.

Other researchers have been able to overcome this problem in split-brain patients.
