We can never really be aware of or live in what we call "now". Because it takes time for our brain to process the information about what's happening now… and it takes time for that information to get from the rest of our body to our brain. So, we live in the past!
Your brain can be considered the most complex organ in your body and the centerpiece of your nervous system. Although your brain works as a unified whole, neuroscientists can identify areas within it that perform specific functions.
The nervous system is a network of specialized tissues that regulates thoughts, emotions, actions, sensations, and basic body functions. The brain on the other hand is the body's control center. The brain sends messages to and receives stimulation from all parts of the body.
