THINKING SKILL

2. What is Brain?
An organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellect...

3. Brain Characteristics
3 = the weight of your brain in pounds
4 to 6 = the number of minutes your brain can survive without oxygen before it starts to die
8 to 10 = the number of seconds you have before losing consciousness due to blood loss
10 to 23 = the number of watts of power your brain generates when you’re awake (that’s enough to turn on a light bulb!)
20 = the percentages of oxygen and blood flow going to the brain
100,000 = the number of miles of blood vessels in your brain
1,000 to 10,000 = the number of synapses for each neuron in your brain
100 billion = the number of neurons in your brain

4. 1.3 to 1.5 kg Brain Size A human brain is around (2.9 to 3.3 lb)
Brain size tends
to vary according
to body size

5. The relationship is not proportional: the brain-to-body mass ratio varies Size doesn’t matter in the brain. There is no evidence that a larger brain is smarter than a smaller brain

7. Brain Structure

9. FUNCTION OF EACH LOBES
The frontal lobes are responsible for problem solving and judgment and motor function.
The parietal lobes manage sensation, handwriting, and body position.
The temporal lobes are involved with memory and hearing.
The occipital lobes contain the brain's visual processing system.

10. HOKA - HOKI
Roger Sperry (1965) succesfully divide the brain (Split-brain)
Devides into 2 regions of brain; Hemisfera Otak Kiri (HOKI) and Hemisfera Otak Kanan (HOKA).

13. Brain Waves

14. Beta 1) Beta (14-40Hz) – The Waking Consciousness And Reasoning Wave
Beta brain waves are associated with normal waking consciousness and a heightened state of alertness, logic and critical reasoning.
While Beta brain waves are important for effective functioning throughout the day, they also can translate into stress, anxiety and restlessness.

15. Alpha Alpha (7.5-14Hz) – The Deep Relaxation Wave
Alpha brain waves are present in deep relaxation and usually when the eyes are closed, when you’re sleeping into a lovely daydream or during light meditation.
It is an optimal time to program the mind for success and it also heightens your imagination, visualization, memory, learning and concentration.

16. Theta Theta (4-7.5Hz) – The Light Meditation And Sleeping Wave
Theta brain waves are present during deep meditation and light sleep.
It is the realm of your sub consciousness and only experienced momentarily as you drift off to sleep from Alpha and wake from deep sleep (from Delta).

17. Delta Delta (0.5-4Hz) – The Deep Sleep Wave
The Delta frequency is the slowest of the frequencies and is experienced in deep, dreamless sleep and in very deep, transcendence meditation where awareness is fully detached.
