  1. TOPIK 3TOPIC 3 Otak Brain EUW322- KEMAHIRAN BERFIKIR 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 grain 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. Brain Size • A human brain is around 1.3 to 1.5 kg (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

  6. Brain Structure

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

  8. Left / Right

  9. Brain Waves

  10. 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.

  11. 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 slipping 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.

  12. Theta • Theta (4-7.5Hz) – The Light Meditation And Sleeping Wave • Theta brain waves are present during deep meditation and light sleep, including the all-important Rapid Eye Movement(REM) dream state. • It is the realm of your subconsciousness and only experienced momentarily as you drift off to sleep from Alpha and wake from deep sleep (from Delta).

  13. 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, transcendental meditation where awareness is fully detached.
