The main, and largest, part of your brain is the cortex. It receives messages, examines them and makes decisions about their importance.
Incoming messages :
Every minute, the cortex receives millions of nerve signals from your body, but they are not all important. This part of the brain identifies the important information very quickly.For example, the sound of a car when you want to cross the street can be very important because it can save your life.
Outgoing messages :
Millions of nerve signals also leave the cortex every minute. The signals go to your muscles and tell them what to do. For example, they tell your legs 'STOP!' when the sound of a car is very near.
