Read in-depth answer here. Simply so, how does the brain work for kids?
The brain connects to nerves that travel throughout the body. Nerves from our senses (hearing, seeing, touch, etc.) send signals to the brain to let the brain know what is going on in the outside world. The brain also sends signals using nerves to muscles in order to make our body move.
Also, why is the brain so important? The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
Keeping this in consideration, how does the brain control the body?
The brain is the body's control centre: it sends messages to your body through a network of nerves called “the nervous system”, which controls your muscles, so that you can walk, run and move around.
How does our brain think?
In order for your brain to think, you need nerve cells that can detect information about the outside world and can transmit that information to other nerve cells. It's the transmission of information, the cells talking to each other, that's the fundamental physical basis for how thinking works.
