Question: How does the brain work and can we fix it when it goes wrong?

Hey Genius-

tricky one. The work is basically a complex mixture of biological wires called neurons. the brain is mainly the cerebrum (around 95 %). In the cerebrum is where we think, how we control our muscles and where our memories form. It has two sides- one which controls things like music, shapes and colours, and the other that controls maths and speech. We know that the right side of our brain controls the left side of our body, and the left side of our brain the right side. There’s a tiny bit at the back of our heads called the cerebellum, which controls all of our balance. He is only 1/8 the size of our cerebrum. In our brain stem (between the cerebrum and the cerebellum) is where we connect to our spinal cord. It sends all the signals to the rest of our body- like how to breath, how to circulate blood, how to digest food. What our brain does is control lots of muscles that work without us thinking (walking, heart beating). It’s also like the most complicated e-mail inbox int he world, and sorts through millions of messages of data everyday. WE also have parts to control how we grow and our temperature. There are also loads of nervous inside our spinal column that feed signals to the rest of the body.
When it goes wrong, we can operate on the different parts of it and fix things like the temperature regulator or the balance detector. Lots of it works just like an electric circuit, and we’ve got pretty good at those. You can actually take out parts of your brain and still be okay. sometimes they can remove memories though, which is pretty scary.
