Cerebral hemispheres
The two hemispheres that make up the front brain, in several places are connected by bundles of fibers, of which the largest and most important is the callous body. The right hemisphere controls the sensory and motor functions of the left half of the body, while the left is implementing a similar control over the right half. With respect to vision and hearing hemispheric control more complicated. As we saw in Chapter 3, the field of view of each eye is composed of left and right halves. The information from the right side of the field of view of both eyes received only in the left hemisphere, and from the left side of the - just to the right hemisphere. The relationship between the visual areas of the left and right hemispheres of the norm through the callous body. Humanity is in contrast to those contralateral functions localized only in one hemisphere of the brain.
The most profound penetration into the secrets of the physiological bases of thought and consciousness has been achieved through clinical research of persons with brain damage (the result of accident, illness or surgery), in particular those resulting from transactions hemispheres were separated from each other.
