The Brain

What weighs about 3 lbs and uses about 20% of your body's energy??
Your brain of course.

Definitely the most complex part/organ of the human body. It controls the whole body consciously and unconsciously. The main part of the brain, which is the largest, is called the cerebrum. It is split into two hemispheres: left and right.

Left hemisphere:
uses logic,detail oriented, facts rule, words and language, present and past, math and science, can comprehend, knowing, acknowledges, order/pattern perception, knows object name, reality based, forms strategies, practical, safe and controls the right side of the body.

Right hemisphere:
uses feeling, “big picture” oriented, imagination rules, symbols and images, present and future, philosophy & religion, can “get it” (i.e. meaning), believes, appreciates, spatial perception, knows object function, fantasy based, presents possibilities, impetuous, risk taking and controls the left side of the body.

The two halves of the brain "communicates" via the corpus callosum. It is sort of a highway for the brain signals. Females have larger corpus callosum compared to men.

I am writing this because I Googled "brain usage" today and found out that the information I have was WRONG. The information was from the TV series Heroes(TV shows cant be trusted these days...sigh..). The information was that the human brain only utilises 10% of the brain. However, the fact is that the human brain uses more than that(close to 100% I believe).

With the results of the search I "played" with my brain a little bit. Testing whether which side of it is more dominant. Look at the image below(got from here):

If you see it spinning clockwise means you use more of your right brain. If it is anti-clockwise means left brain. The first time I looked at it it was spinning clockwise but I sort of made it spin the opposite direction as well. Next test was from this website.

My results:

Your Brain Usage Profile:

Auditory : 28%
Visual : 71%
Left : 52%
Right : 47%

You exhibit an even balance between left- and right- hemisphere dominance and a slight preference for visual over auditory processing. With a score this balanced, it is likely that you would have slightly different results each time you complete this self-assessment quiz.

You are a well-rounded person, distinctly individualistic and artistic, an active and multidimensional learner. At the same time, you are logical and disciplined, can operate well within an organization, and are sensitive towards others without losing objectivity. You are organized and goal-directed. Although a "thinking" individual, you "take in" entire situations readily and can act on intuition.

You sometimes tend to vacillate in your learning styles. Learning might take you longer than someone of equal intellect, but you will tend to be more thorough and retain the material longer than those other individuals. You will alternate between logic and impulse. This vacillation will not normally be intentional or deliberate, so you may experience anxiety in situations where you are not certain which aspect of yourself will be called on.

With a slight preference for visual processing, you tend to be encompassing in your perceptions, process along multidimensional paths and be active in your attacking of situations or learning.

Overall, you should feel content with your life and yourself. You are, perhaps, a little too critical of yourself -- and of others -- while maintaining an "openness" which tempers that tendency. Indecisiveness is a problem and your creativity may not be in keeping with your potential. Being a pragmatist, you downplay this aspect of yourself and focus on the more immediate, obvious and the more functional

I guess I use both sides equally?? More brain facts here.
