The Brain Galaxy
Transcript of The Brain Galaxy
The brain is grey. It's grey because the neurons that make up the brain are grey. It weighs about 3-5 pounds, which is as heavy as a dictionary. It feels like a soft cube of tofu some surgeons say. The brain is compact and doesn't break apart easily when you cut it. However, a damaged brain feels a lot softer just like toothpaste and breaks apart easily.
The Brain Basics

The Four Lobes of the Brain
The frontal lobe is for abstract thinking, problem solving, judgement and motor function.
The parietal lobe manages sensation, handwriting and body position.
The temporal lobe involves memory and hearing.
The occipital lobe is used for seeing things.

A neuron is a brain cell that transfers information from the brain to the body and the body to the brain. The dendrites reach out and get messages from other cells. The cell body processes the message and decides when to send the message. When the message is ready to be sent it goes through the the axon, a long cable that sends information and stops at the synapse. The synapse is the part when messages travel from one neuron to another. When a neuron gets simulated it triggers an impulse. If the impulse is strong enough it triggers the neuron to take the message to the brain.
Humans have 100 billion neurons. Information sent by the neurons can travel from 1 to 268 miles per hour.
These are different pictures of neurons firing.
Three Things to do When You're Feeling Nervous
1) Think about the situation in a different way. Be positive. Refocus your thoughts and be calm.
2) Think about what you're doing and how you do it. Focus on what you
do, not on what you can't.
3) Breathe in slowly, count to 4, breathe out slowly and count to 4. This process is called square breathing.
Different learning environments can affect your intelligence because an environment with no active learning will result in having less information and intelligence. For example, there were two sisters and one was sent to a learning camp while the other was sent to a fun camp. The sister who went to the learning camp will be smarter because she had opportunities to learn. Her environment was filled with books, science experiments and other learning activities. The other sister that was sent to the fun camp won't be as smart because all she did was sleep, drink soda, eat pizza, play video games and watch T.V. She was deprived of the chance to learn and will grow up to be lazy and unintelligent.
Benefits Exercise can do For Your Brain
The more you exercise the more your stem cells grow resulting in a refreshed brain and body. Exercise also stimulate nerve growth factors.
More about Neurons
Something you can do to stimulate a neuron and make new connections is to learn something that you didn't know about before. To make a connection you need to stimulate the brain at least 10 times.
Working memory lasts for a few seconds to a minute and can only hold up to seven things at a time. Working memory is like a pathway into long-term memory. But first to get to working memory you need to be focused on something.
For working memory to get to long-term memory it needs to be encoded and the encoding happens in the hippocampus. It's the part of the brain that does most of the encoding. Sometimes new information catches on the runways in your brain that you already made connections with. That's another way working memory can get to long-term. A type of working memory is the 7 days of the week, it used to be a working memory till it got converted to long-term memory.
Long-term memory lasts for days, weeks, months, years or your entire life. Long-term memory starts when you find a connection to something permanent and memorable. Some things you have in long-term memory is your name, the seven days of the week, your age, your birthday and your parent's name.
Sensory memory only lasts for a few milliseconds. It stores everything for a short time.

How I can Use What I Learned in Brainology
Brainology helped me understand how my brain works. I know about different types of memory and different types of learning environments. I can use what I learned in Brainology to help enhance my environment by adding different things to help me learn. I know what to do when I feel nervous. I also learned better ways to study. Learning about the brain made me smarter therefore my neurons are growing and making new connections.
Grit and Persistence
Someone I learned about who has grit and persistence is Malala Yousafzai because she was courageous and fought for the rights to learn. The Taliban shot her in the head for going to school but she survived. She is now a spokesperson for human rights, education and women's rights. She received numerous peace awards and is the youngest person to be nominated for the Nobel Peace Prize in 2013.
How Brainology Affects My Daily Life and Study Plans
Brainology affects my daily life because I now know what will make me and my brain healthier. Instead of watching T.V all day, I could go out and exercise, read thick novels or study for upcoming tests. The progress in my study plans includes making more study guides, studying with friends, finding things that relate to my subjects and having discussions with my parents about my work.
These are part of a pneumonic called BRAIN. Pneumonics are when you turn words or objects into phrases you can easily understand.
