Gazzaniga studied split brains - separated from each other.

We projected an image to the right visual field - that is, to the left hemisphere, which is where speech is.
The left brain is dominant for language and speech. The right excels at visual-motor tasks.

Each hemisphere was shown four small pictures, one of which related, to a larger picture also presented to that hemisphere.

The patient had to choose the most appropriate small picture.
The right hemisphere - that is, the left hand - correctly picked the shovel for the snowstorm- the larger picture; the right hand, controlled by the left hemisphere that is,theright hand, correctly picked the chicken to go with the bird's foot.- it's big picture.
Then we asked the patient why the left hand - or right hemisphere - was pointing to the shovel. Because only the left hemisphere retains the ability to talk, it answered. But because it could not know why the right hemisphere was doing what it was doing, it made up a story about what it could see - namely, the chicken.
It said the right hemisphere chose the shovel to clean out a chicken shed.

It said the right hemisphere chose the shovel to clean out a chicken shed.
- M.S.G. We then asked the left hemisphere - the only one that can talk - why the left hand was pointing to the object. It - the left hemisphere - really did not know, because the decision to point to the card was made in the right hemisphere. Yet, it had made up an explanation.

the study and the conclusions are the only slim example I can find That says when the brain is in an an ongoing uncertainty over what is presentedwith, It requires an explanatory account - in schizophrenia , with overloading perceptions persisting the brain must simplify and answer.
