Document Summary
The left and right hemispheres are joined by the corpus callosum. In the 1950s, it was discovered that when this connection between the two halves is cut, each hemisphere. In studies conducted on cats, the corpus callosum was cut along with the optic chiasm. Thus, visual information from the left eye was dispatched only to the left brain, and information from the right eye was dispatched only to the right brain. If the animal had the left eye covered, he could learn to perform a task (object discrimination) with the right eye. If the right eye was covered and left eye exposed (opposite scenario), he would have to relearn the task. Thus, the animal had no recognition of the problem and had to learn it again with the other half of the brain. functions independently as if it were a complete brain. In humans, the same type of operation was done, except there was no lesion of the optic chiasm.
