2.6 Left and Right Brain Decodification of Visuals

The brain has two hemispheres connected with fibbers in the corpus callosum. If the corpus callosum did not exist, or if it was surgically severed, visual and auditory information input from the left eye and ear would reach only the left hemisphere, and vice versa, as the optic and acoustic chiasma that allows the criss‑crossing of the information reaching the brain would no longer exist.

Extensive correlated studies that started with brain surgeries mostly on epileptic patients and the latest neuroanatomical and neurophysiologic ones that use deoxyglucose to identify which part of the brain is more active have confirmed that recognition of images is a function of the right brain.

Underlining the tasks of the right brain, Ornstein stated that: If the left hemisphere is specialized for analysis, the right hemisphere seems specialized for holistic mentation. Its language ability is quite limited. This hemisphere is primarily responsible for our orientation in space, artistic endeavour, crafts, body image, and recognition of faces. It processes information more diffusely than does the left hemisphere and its responsibilities demand a ready integration of many inputs at once. If the left hemisphere can be termed predominantly analytic and sequential in its operation, then the right hemisphere is more holistic and relational and more simultaneous in its mode of operation.

Image recognition is a function of the right hemisphere of the brain that controls the left side of the body. Pictures are typically images of objects of the real world. Consequently, picture recognition is a function of the right hemisphere of the brain. Recognizing a television picture that combines visuals, sounds, and motion is a holistic process, a task performed by the right brain.
