Left vs. Right Hemisphere of the Brain: Which Dominates You?

The human brain is a complex and interconnected system, the largest and the most functionally important part of the central nervous system. Its functions include processing of sensory information coming from the senses, planning, decision making, coordination, motion control, positive and negative emotions, attention and memory. The highest function performed by the brain is thinking.

dominant hemisphere testYou can easily find out which of the hemispheres of your brain is active at the moment. Look at this picture.

If the person in the picture is rotating clockwise, your left hemisphere is more active at the moment (logic, analysis). But if he is rotating counter-clockwise, then your right hemisphere is more active (emotions and intuition).

In which way is he rotating to you? At some effort, you can make the person rotate in any direction. To start, try to focus on the picture. Do you find it difficult? Want to know how does it work? Check out this article on optical illusions for more details.

If you are looking at the picture together with someone else, very often you can see it rotating in two opposite directions at the same time. It is normal, just different hemispheres of your brain are active at the moment.
 

Areas of specialization of the left and right hemispheres of the brain



Left hemisphere

The main field of specialization of the left hemisphere is the logical thinking, and until recently this hemisphere has been considered dominant. But in fact it dominates only while performing the following functions.

The left hemisphere of the brain is responsible for language skills. It controls speech, reading and writing abilities, spelling, memorizing facts, names and dates.

  • Analytical thinking
  • Literal understanding of words
  • Sequential processing of information
  • Mathematical capabilities
  • Right part of the body
Right hemisphere

The main field of specialization of the right hemisphere is intuition. As a rule, it is not considered dominant. It is responsible for the following functions:

  • Perception of non-verbal information
  • Spatial orientation
  • Musicality
  • Understanding of metaphors
  • Imagination
  • Emotions
  • Sex
  • Mystics
  • Dreams
  • Multitasking and parallel processing of information
  • Left part of the body

      try to look at some beautiful pictures or think of smth that provokes feelings and emotions
      it will activate your right hemisphere and you will see it rotate counter clockwise

        Totally, I wondered if this would happen, so I recited some poetry and thought about some paintings, sure enough, the direction changed!

    This is neat. After a few minutes of practice I was able to see the head rotating in one direction and the rest of the body rotating the opposite direction at the same time.

    I can’t see it go counter-clockwise either. Tried writing with my left hand, listening to music, and looking at pictures. Perhaps I don’t have a right brain.

    At first i ONLY saw it moving counter-clockwise but after a while i was able to choose which way it moved by looking at her legs with just my peripherals. I could see it change from clockwise to counter-clockwise and whichever one i saw when i focused on it was what it was. weird

    That’s funny, for me the direction constantly changes.

    Its an interesting illusion but nothing to do with right/left hemispheres.

    ORLY?
    First she rotates CW for me. 5 minutes of listening music, looking at animation with right peripheral sight and viola! How she CANT rotate CCW? 🙂 Next, turn music off, practicing multiplication table and logarithms for some time… CW again.
    However, maybe I just fooling myself.

    Something interesting. So I am left hemispherical by default. The right hemisphere is fr visual and creative skills but also sex is on the list.

    I am finding that whenever I focus on the feet of the model it turns counter clockwise suddenly for the right hemisphere. Having a foot fetish I think it might be triggering the right hemisphere for me.
