How the brain works


the brain is the most fascinating part of the human body not much to look at, it resembles a spongy mass of tissue feels like tofu and weighs roughly four tubs of butter our brain is actually made up of mostly water, and about ten percent fats while our brain only makes up approximately two percent of the entire body’s weight it uses a massive twenty percent of the body’s energy the brain’s basic building blocks are known as neurons and we have around one hundred billion of these each with between one thousand to ten thousand connections to other neurons creating neural pathways, or ‘roads’ within the brain there are literally trillions of neural connections within the brain similiar to a city’s electrical power grid, information is passed along these roads through a series of chemical messages, and electrical impulses as all of this activity takes place, our brain generates between ten to twenty-five watts of power enough to power a light bulb over the course of one day, your brain generates more electrical impulses from firing neurons than all of the telephones in the world so really, your brain isn’t just a spongy mass of tissue it’s your most complex organ: a power station that connects your every thought, movement, and feeling and it’s firing right now

  1. Brain is not only power centre in the head, there must be one more subtle invisible power centre in the head and that is mind that is actively involved in judgement making

  2. Love the animation in this video!
    But most sources say the brain is 60% fat and this video says 10% fat. Anyone know why?

  3. Beautiful!
    However,another video states that there are about 400 billions neurones, not 100 billion as this video mentioned. Clarification please….
    This piece of info will confuse students.
    Accuracy in important when making videos

  4. PrecXx B.: From our understanding, current academic thought is the average brain has 100 billion neurons at adulthood. See Changeux, Jean-Pierre. (1985). Neuronal Man: The Biology of Mind. Or just check out Google Scholar.

  5. The brain doesn't seem to have any data storage capabilities. So where does memory resides? And how is a particularly neural pathway formed repeatedly when it could easily branch out to varied of directions when presented with the same stimuli? Since our brain is constantly learning, how is it programming itself? Is there are brain languge that only the brain knows?

  6. Ms. Andreasyan:
    1. I didn't know about the brain synapsis and telephone comparison.
    2. The synapsis process and what it does and also what the brain feels like (it said the same thing in the book)

  7. There is actual neural tissue lining the digestive system that is nicknamed "The Second Brain" which seems to play a key role the emotional state of a person. Working in tandem with the brain in your head in that department.

  8. May I please have permission to use this video for a 7th grade powerpoint research project on how the brain works?

  9. Thank you so much for these videos, they have helped again and again, I recommend anyone who is delivering learning in our Studnets Union to watch these!

  10. Thank you for the video. We have shared the video on our Wonders of the Brain facebook page. https://www.facebook.com/WondersoftheBrain
