Cerebral Dominance

Cerebral Dominace in  Famous People

§  Cerebral dominance is the ability of one cerebral hemisphere (commonly referred to as the left or right side of the brain) to predominately control specific tasks.


This term refers to the fact that one of the cerebral hemispheres is "leading" the other one in certain functions.


celebrities who are more dominant on his Right  hemisphere of brain

   These people became famous because they developed many abilities such as : the facility for imagine paintings, to make sculptures, music, in the area of big films, and  for the capacity of the speech, reading and writing.



Miguel Angel Buonarroti
   Was a sculptor, architect and Italian Renaissance painter, considered one of the greatest artists in history both for his sculptures as paintings and architectural work.




                                                                                          Ludwig van Beethoven 
     Was a composer, director of orchest  and pianist German.

Oprah Gail Winfrey 
   Is a television presenter, actress, entrepreneur, and producer ( she has a lot of  facility of speech ).

   For another part… these people became famous because they developed many abilities in the area of science and for his contribution at the humanity in an analytical and logical information.


Albert Einstein 


    Was a German physicist. Is regarded as the greatest scientist of the twentieth century, published the most famous equation of physics at the grassroots level, is the mathematical expression of mass-energy equivalence, E = mc ²




Sir Isaac Newton
   Was a physicist, philosopher, theologian, inventor, alchemist and British mathematician, author of “Philosophiae naturalis principia mathematica”, where describing the law of universal gravitation and laid the foundations of classical mechanics with the laws that bear his name.

Cerebral Hemispheres



Differences between the Left and Right sides of the brain


   
  By means of a prominent groove, called the longitudinal fissure, the brain is dividid into two halves called hemispheres. At the base of this fissure lies a thick bundle of nerve fibers, called the corpus callosum, which provides a communication link between the hemispheres. The left hemisphere controls the right half of the body, and vice-versa, because of a crossing of the nerve fibers in the medulla.

      Although the right and left hemispheres seem to be a mirror image of one another, there are important functional distinctions.



    The left-brain and the right-brain are known by numerous synonyms. Respectively, these are: male brain and female brain, the major hemisphere and the minor hemisphere, the sequential thinker and the holistic thinker, the inchworm and the grasshopper, the logical brain and the creative brain, the artist and the thinker.

  The question is: why are the two sides described by such antonyms? For answer this question I found a image that show why ...




   Experimentation has shown that the two different sides, or hemispheres, of the brain are responsible for different manners of thinking.




The following table that I made for you illustrates the differences between left-brain and right-brain thinking:

PARTS OF THE BRAIN

The Brain

   The brain is the control centre of the body – and it controls every single thing that we do, including our emotions, sensation, movement, and thinking.

   The brain grows at a rate of 250,000 cells per second in a foetus, and is fully grown by the time a person is 15 years old. By this stage, the brain weighs about 1.5 kilograms, and is the texture of half set jelly.



Hemisphere Brain Function 

   The brain is divided into two halves called hemispheres. Usually, the left half of the brain controls the right side of the body. The right half of the brain controls the left side of the body.


Lobes of the Brain 

Each hemisphere of the brain is further divided into 4 lobes: frontal, temporal, parietal and occipital.

Below you can see which lobe is responsible for which function:

Ø  Frontal lobe: Conscious thought; damage can result in mood changes.
Ø  Parietal lobe: Plays important roles in integrating sensory information from various senses, and in the manipulation of objects; portions of the parietal lobe are involved with visuospatial processing.
Ø  Occipital lobe: Sense of sight; lesions can produce hallucinations.
Ø  Temporal lobe: Senses of smell and sound, as well as processing of complex stimuli like faces and scenes.
