The human brain: 100 billion cells
by Rubin




Ever think about your brain? Well, the human brain is a very complicated organ. The brain consists of many different parts, but we dont care about that, we only care about one part, the thinking part. The brain is one of the most curious mysteries to most, but once you know a little bit about it the brain make alot of sense. 
How the brain works

The brain is not a simple thing, 100 billion cells is pretty difficult to grasp. To help you remember how the brain works I broke it up into 5 main parts to make it more understandable.



1. The frontal lobe:
          In the red area of the brain, you can see the frontal lobe. The frontal lobe is responsible for controlling impulses, controlling judgment, language production, working memory, motor function, problem solving, socialization, spontaneities, planning, coordination, and executing behavior. This may seem like a lot functions for just one part of the brain, However after careful reading I realized a lot of the functions relate and overlap each other.

2. The parietal lobe:
          In the brown area of the brain you see the parietal lobe. the parietal Lobe is responsible for reading touch and body position. The parietal lobe receives the brain waves for for the nervous system. the parietal lobe combines nerv information from different modalities, mostly determining spatial sense and navigation. It is associated with movement, orientation, recognition, perception of stimuli.

3.The occipital lobe:
          In the dark green area of the brain you can see the occipital lobe. the occipital lobe controls our visual perception. The Prostrate region of the occipital lobe discriminates between colors and processes movement.
Visual perception is important because it stops us from running into trees and things infront of us, by triangulating with our eyes we can fing the distance of things by processing it with our occipital lobe.

4. The temporal lobe:
          In the light green area of the brain you can see the temporal lobe. The temporal lobe is responsible for processing sound. When a temporal lobe is not functioning It is impossible to understand someone with out reading there lips. The temporal lobe is very important in everyday life and it is used to decipher answers to almost 9,000 thousand words we say every day.

5. The cerebellum: 
          In the blue you can see the cerebellum. The cerebellum is responsible for controlling you coordination  balance, voluntary motor movements, sense of position of the different parts of your body, equilibrium, muscle tone, and your fine motor skills. These skills control your Ability to write and type as well as much more physical actions like shooting a basketball or catching a football. Next time you think you have a "bigger brain" than a "dumb jock" think again.

  1. HI Rubin,
    Great blog! Your beginning was very intriguing and I thought that all the information you gave about the different parts was really interesting. It really made me think about how I use different parts of my brain. For example my balance is not very good, so maybe my cerebellum needs strengthening. Even though each part of the brain has its functions, does each part operate separately or does the brain work as a whole? Great blog! You really brought up some great points!

  2. Hi Rubin,
    I really liked your blog! It is really interesting to think about how your brain really works and functions. I have never really thought about how my brain works, because it seems very complicated, but you explained it really well, and I didn't have trouble understanding anything. I liked how you separated the brain into 5 parts, because it was easier to see which parts you use at which times. Is there one part of the brain that is most commonly used by humans, or are they mostly equally used? Great blog, it was really interesting!

    Thanks,
    Jessica

    1. hey Jessica,
      Thats a great question! To be honest I do not know but heres a link to some brain activity imaging https://www.google.com/search?ix=seb&q=brain+activity+images&um=1&ie=UTF-8&hl=en&tbm=isch&source=og&sa=N&tab=wi&authuser=0&biw=1279&bih=702&sei=DDBZT7juIsHTiAKuq_WbCw
      I do not truly know the answer but the images suggests the cerebellum is the most commonly used. I suspect that sitting in a MRI may have some effect on the patients's brains. The parts of the brain being used depends on what you are doing.

  4. Rubin,
    Nice job demonstrating the brain with a visual representation. It really helped my occipital lobe understand the information. I have one question though, how does the brain get these messages to the other parts of the body so that it can respond?
