  • What is up with this idea of people being left-brained and right-brained?

  • Is it a myth?

  • Actually, no.

  • The thing is some people are more left-brained and others are more right-brained.

  • We found out what determines which side has dominance happens before we're even born.

  • In the womb, when our spine develops, the way they wire up to our developing brains determines which side is dominant.

  • Why do we have a dominant side?

  • Lateralization

  • This refers to some brain functions taking place in one hemisphere or one side, rather than the other.

  • Each hemisphere controls a different body side as well.

  • Your dominant brain side connects to your dominant body side.

  • The left side of the brain controls the right side of the body.

  • And the right side, the left.

  • This cross-wiring neural pathway means, if you are left-handed you are more relying on the right side of the brain.

  • And again vice versa.

  • How does this affect our thinking style?

  • The left side and the right are responsible for very distinct thinking patterns.

  • Generally, the right brain thinks in pictures instead of words.

  • Using intuition and focusing on the bigger picture.

  • The left focuses on actual words.

  • Thinking in a very verbal way.

  • Honing into details first, and then putting them together to form a whole picture.

  • It's widely agreed upon that the right side is creative and the left is logical.

  • How is language affected?

  • The left side is good for vocabulary, grammar, and literal meanings.

  • The right side is great for intonation and accentuation, basically, how we speak.

  • How is music heard in the brain?

  • We already know the right side is more creative.

  • Music processing takes place in the entire brain.

  • With the right side focusing on the melody, while the left side focuses on the motor scale your hands need to play the instrument.

  • Is it true that math is left-brain business?

  • We assume the left side, being more logical, does more math.

  • Things such as counting, adding, subtracting, etc.

  • The right, however, actually helps with estimating amount of sets of objects.

  • While your left brain might help you take a test, the right brain can tell you how many boxes are still on the delivery pallet at work.

  • Which side handles the memories?

  • The hippocampus is actually the part of the brain associated with memory.

  • And it occupies both sides of the brain.

  • The left side has been deemed more important for storing memories, as its strength is in retrieval.

  • The right side is good for reciting, like multiplication tables.

  • Which side will help me more in wilderness survival camp?

  • Depending on our situation, the sides we depend on change.

  • Studies have shown that in warm places with more calm moods and less risks to your life, the right side is better.

  • The left kicks in when it's cold;

  • the food is scarce, and threats to your life like unyielding polar bears are abundant.

  • Survival skills are based more on spatial awareness and logic,

  • not creativity.

  • So the left side controls more of our ability to survive.

  • How does damage to the right side affect a person?

  • Damage to the right side could lead to self harm and even suicide.

  • An overactive right side can cause feelings of depression and angst.

  • It can also cause problems with language and perception, such as the lack of emotion while speaking.

  • How does damage to the left side affect a person?

  • Left-side damage affects vision.

  • There is a reduction in spatial frequency,

  • so we only see the larger parts of an image.

  • Speech also seems to be littered with grammatical errors.

  • This is called Broca's aphasia.

  • So, which side is superior?

  • It's important to stress that there is no right or wrong way to think.

  • Both sides have their advantages and simply represent two ways of thinking.

  • If you want to increase your brain power, work on both sides of your noggin.
