    Brain And Its Functions Part 1 17203 Brain And Its Functions Part 1 17203 Presentation Transcript

    • Shared by Dr.K.Prabhakar Brain and Its Functions-Part 1
    • Presentation
      • This slide show provides you information on basic facts about brain.
      • You may have to go the Part 2 for understanding about brain functioning and role of nurturing brain.
      • This presentation have been divided into four parts .
      • You have to go through it sequentially to understand Brain and its Functions in the context of Management disciplines in the absence of my intervention.
    • Early weeks crucial
      • Human embryo - just 6 weeks after conception.
      • All the parts have been in place for two weeks, and brain waves are now detectable
    • NEURON
    • Brains of human and comparison with other animal brain
    • The Triune Brain
      • Neocortex - Thought (including planning, language, logic & will, awareness)
      • Limbic System - Emotion (feelings, relationship/nurturing, images and dreams, play)
      • Reptilian Brain - Instinct (survival, breathing/swallowing/heartbeat, startle response)
              • Three Brains in One
    • Reptilian Brain
      • The brain stem part of the brain, is the most ancient -- it evolved 500 million years ago and is more like the entire brain of present-day reptiles.
      • For this reason, it is often called the reptilian brain .
      • Various clumps of cells in the brain stem determine the brain's general level of alertness and regulate the vegetative processes of the body such as breathing and heartbeat.
    • Reptilian Brain
      • The brain stem is the reptilian brain. It is a remnant of our prehistoric past.
      • The reptilian brain acts on stimulus and response. It is useful for quick decisions without thinking.
      • The reptilian brain focuses on survival, and takes over when you are in danger and you don’t have time to think.
      • In a world of survival of the fittest, the reptilian brain is concerned with getting food and keeping you from becoming food.
      • The reptilian brain is fear driven, and takes over when you feel threatened or endangered.
    • The Ancient Limbic System
      • The modules that lie beneath the corpus callosum are known as the limbic system .
      • This area is older then the cortex in evolutionary terms and is also known as the mammalian brain because it is thought to have first emerged in mammals.
      • This part of the brain, and even that below it, is unconscious , and yet has a profound affect on our experience because it is densely connected to the conscious cortex above it and constantly feeds information upwards.
      • The limbic stem is the root of emotions and feelings. It affects moods and bodily functions.
    • The Ancient Limbic System
      • Emotions, our most basic reactions, are generated in the Limbic system along with the many appetites and urges that help us behave in such a way to survive.
      • For instance, the Amygdala , is the place where fear is registered and generated.
      • The neocortex is the most evolutionary advanced part of your brain.
      • It governs your ability to speak, think, and solve problems.
      • The neocortex affects your creativity and your ability to learn.
      • The neocortex makes up about 80 percent of the brain.
    • End of Part 1
