I don't know about you, but I think the brain is the most fascinating part of our body. Out of all the parts of the human body, the brain is the one thing that we have yet to fully discover and study. The human brain is even more complex than any other known structure in the universe.
Not only does the brain allow us to move and coordinate every part of our body, but most importantly, the brain also allows us to understand and remember anything and everything we learn and experience from our day-to-day living.
The brain literally enables us to function!
What’s inside the brain?
The brain is made up of fat and protein and weighs about three pounds. All of that is just two main types of cells – glia and neurons.
Let’s talk about glia first. Glia (“glue” in Greek) are primarily responsible for insulating each neuron and holding them in place, for transporting nutrients to neurons and for cleaning up unwanted debris like dead neurons and pathogens. Recent research has also proven that glia play an active role in facilitating the communication between neurons.
What we’ll be focusing on are the neurons or nerve cells, which transports information to and from other neurons or other cells of our body. Aside from the cell body itself, every neuron has an axon, dendrite and synapses, where the dendrites and axons connect.
There are about 100 billion neurons in our brain, and each neuron can have 1000-2000 synapses. There are pretty much more neurons in our brain than there are stars in the galaxy.
Doesn’t it sound like there’s an entire universe inside our brain?
How does our memory work?
Let’s say you were scrolling through Instagram when you saw a post by Oprah where she was talking about Michelle Obama’s memoir called “Becoming” and how it is an inspiring read.
As you view Oprah’s post, this is what happens in your brain:
The information is received – you see an image of Oprah, Michelle Obama’s photo on the book cover, the book’s title, the couch Oprah was sitting on, you hear the background noise when you play the video, etc.
Key information is selected – you focus on specific details from the post like the person who wrote the post, the book title, whose memoir it was, what the book cover looks like, when the book would be available, etc.
The information you selected gets stored in your brain – in other words, you end up remembering those key details.
What we just talked about are the three types of memory: sensory memory, short-term memory, and long-term memory.
Brain anatomy
Everything you do is encoded in your brain. Your habits, your memory, your exam books, your feelings.
But which parts of the brain play big roles in remembering?
Prefrontal cortex - This is where immediate information is processed.
Hippocampus - Which is in the brain's temporal lobe, on the sides of our head.
Neocortex - Whatever was processed in the hippocampus is then known to be transferred to the neocortex as knowledge.
Now you have a better idea on how the memory process works and which parts of the brain play big roles in remembering.
Want to go in depth into how the brain works and learn the four steps for “encoding” what you want to remember?
Ideally, every important piece of information should be stored in long-term memory. It would definitely be helpful if everything we’ve ever learned in school is safely stored in long-term memory so that every quiz or exam would be a piece of cake. Not to mention, remembering important dates or milestones in our own lives and our loved ones’ lives can save us from a lot of trouble too.
It would be fantastic if everything we want to remember would get stored in our long-term memory automatically. Unfortunately, that doesn’t always happen.
Luckily, there are things that you can do to help you focus and remember things better:
Like playing music while studying? Instead of playing music with lyrics/words, go for instrumental music or nature sounds. Brain.fm is my favorite, and there’s a FREE version too.
Try to “apply” your knowledge as soon as you’ve learned them. A quick way to do this is to quiz yourself in your head or to take an actual quiz on paper or through your computer/phone.
SLEEP a lot. Our brain makes connections when we sleep, so ensuring you have enough sleep will also help you remember things better.
Eat healthier. No, this isn’t about going on that trending diet at all. Simply eat a well-balanced meal that will help improve not just your memory but also your productivity at school or work.
That’s it? Nope, there are still more things that you can do. For example, you can also “wake up” and train your memory so that you can remember things more efficiently.
Can we really train our memory?
Yes, we can!
Journalist Joshua Foer (author of “Moonwalking with Einstein”) was writing about memory champions from around the world. One day, a memory expert asked Joshua if he could train him. Joshua reluctantly accepted the challenge and trained 1-2 hours a day, everyday for a year. The goal was for this normal journalist, with a very average IQ and memory, to win the USA Memory Championship.
As you may have guessed, he did become the memory champion!
Joshua’s story fascinates me because this proves that memory is a trainable skill. Just like you have to work out regularly to get that 6-pack, you can sharpen your memory if you work hard at it.
