About the brainSome important facts about the brain are: 1) the weight of the brain is 1.2-1.35kg. 2) There is no relation between the size of man’s brain and its wisdom and cleverness. 3) Nerve signals pass to and from the brain at a velocity of about 720 km/hr. 4) Thickness of brain’s cortex in which consciousness and memory are located is 3-4 mm and its area is about 2500 cm2. 5) The brain with respect to its size needs energy 5-10 times more than other limbs. Fig.1 [2] by Alex Grey (1953), an American artist specializing in anatomy of the body, is an artistic demonstration of the brain.

The structure of the brainThe brain is located in the skull as demonstrated in Fig.2 by an unknown artist. Fig.3 shows bottom (left) and top (right) views of the brain. The bottom view is an artwork by the Israeli artist Eli Gur Aryeh (1964) and that on the center by an unknown artist. On the R.H.S is a surrealistic top view of the brain that appears on the cover of the book “The Creative Code” by Noam Manela. Fig.4 is a surrealistic view of back, front and top views of the brain. Observing the top view of the brain in the center of Fig.3 shows it is two-sided: right hemisphere and left hemisphere. Both operate slightly different but they communicate through the corpus callosum tissue. Fig.4 (right) demonstrates artistically the fact that practically the two halves are not the same.

The left hemisphere [3] in the center of Fig.3 specializes in analytical thoughts. It is responsible for details, knowledge, definitions, planning, goals, words, productivity, efficiency, science, technology, stability, extraversion, physical activity, and the right side of the body. The right hemisphere [3] in the center of Fig.3 is responsible for intuition, feelings, sensitivity, emotions, daydreaming, visualizing, creativity, color, spatial awareness, first impressions as well as recognizing patterns and similarities and combination of these elements into new forms.

Fig.6 demonstrates a longitudinal-section of the brain where the role of each part is as follows. The corpus callosum enables the two halves of the brain to communicate. The pons operates as transmission station to sensational and movement paths. The medulla oblongata controls non-voluntary functions such breath and contraction of blood vessels. The cerebrum controls all voluntary activities and mental processes. The cerebellum is involved in the coordination of voluntary motor movement, balance and equilibrium and muscle tone. And finally the spinal cord. It is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain (the medulla specifically). The brain and spinal cord together make up the central nervous system.
Fig.7 is an interesting artwork by Alex Grey [5] demonstrating how the senses seeing, hearing, smelling, and taste return a feedback to the brain where they are processed.
Performances of the brain via artThe brain is an organ in the central nervous system that is responsible of all our performances and controls emotions, vision, hearing, sight, movement, sleep, thinking and other important functions. The three parts of the brain, the forebrain, midbrain and hindbrain, are responsible for carrying out these functions. In the following we demonstrate by art the above performances. Fig.8 by an unknown artist demonstrates the action of smelling. Figs (9, 10) and (15) were painted by the Czech artist Oliver Solga (b.1954) where in Fig. (9) it is emphasized artistically that smelling is eventually via the brain. The function of “hearing” in Fig (10) is demonstrated by inserting into a brain the image of the screamer of the famous artwork “The Scream“by the Norwegian expressionist artist Edvard Munch (1863-1944). It should be noted that “hearing” (Fig.10) is defined as “perceive (sound) via the auditory sense” where “listening” (Fig.11) by an unknown artist is defined as “hear with intention”. Fig.12, “The Librarian” [6], was painted by Giuseppe Arcimboldo (1527-1593) who was an Italian painter best known for creating imaginative portrait heads made entirely of such objects as fruits, vegetables, flowers, fish, and books. The location of the books in the painting demonstrates that the action of “learning” is executed by the brain. Figs.13, 14 and 16-21 demonstrate “thinking”, the most important action of our brain. Fig.13 is the famous sculpture “The Thinker” [7] by Auguste Rodin (1840-1917), a French artist, most famous as a sculptor. Fig.14 is a sculpture constructed by the Israeli artist Mrs. Tova Aloni.
