learn about the brain and nervous system
your brain and your nervous system work together to help you do things like see, smell, taste, feel, and move. your nervous system sends signals to your brain to control these important functions. it also takes messages from your brain to your muscles, organs, and skin. but sometimes there is a problem, and the signals can't be sent. for example, with parkinson's disease, nerve cells in the brain break down and can't send signals, so you may have trouble moving the way you want to. other problems, like vertigo, happen when your sensing systems send false signals to your brain.
