I will praise you
because I have been remarkably and wondrously made.
Psalm 139:14 CSB
"In 1983, Sergent reported her research on a split- brain patient who was presented with conflicting messages in each of the two isolated visual fields. The patient was able to respond to the conflicting information with perfect accuracy with either hand, even though each hand was controlled by a cerebral hemisphere that saw only one of the messages. She concluded that the patient could integrate and
In 1986, Sergent reported on a split-brain patient who could integrate visual information, such as whether two lines were aligned or would meet at an angle greater to or less than 90 degrees. showed an accuracy that was well above chance even though no part of the brain “saw” both images.
Again, in 1987, Sergent also reported research on two split-brain patients to whom she presented partial information in each of the split visual fields. Neither field was given enough information to make a final decision. Again the patients made an appropriate decision in most of the trials. She called their unity of consciousness “perceptual disunity and behavioral unity.”
Thirty years later, in 2017, neuroscientist Yair Pinto and his colleagues concluded, after reviewing decades of split-brain research, that the most accurate summary of the research is this: Split-brain patients have split perception but unified consciousness.
And she said, “Tell me what concept links one of the pictures of the three to the other picture in the other hemisphere.” And split-brain patients would always get it right. For example, in that instance, they would say, well, art is what links the violin and the artist’s palate, the toilet plunger and the light bulb have nothing to do with the violin, really.
And she did it with hundreds of different trials of hundreds of different mixtures of pictures. And people with split-brain surgery were virtually always able to easily identify the concept and pick out the related images, even though no part of their brain saw both images."
