Cool Facts about the human brain
The three pound wrinkly mass in your head might not look like much, but itâs a powerful master control panel. One scientist called it âthe most complex thing we have yet discovered in our universe.â Inside your brain are billions of microscopic cells called neurons. Neurons send electrical and chemical messages to your body.
- Your neurons are joined by tiny pathways or roads. When you do something a lot â like ride your bike â the pathways in your brain that send messages about bike riding are strengthened. This is sort of like a walking path that you walk on every day.
- If you donât do something very often, the pathways become weak. Imagine an old pathway filled with grass and weeds. Practice really does make perfect because it strengthens neural pathways.
If youâre not good at math, start practicing. Chances are, youâll get better.
- Your brain sends more messages everyday than all the phones in the world. Now thatâs a lot of texting!
- Messages can fly from the nerves in your body to your brain at more than 150 mph. Whew!
