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
  • 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.
