HOW YOUR BRAIN PROCESSES INFORMATION?

Your nervous system is filled with circuits made up of neurons that relay messages around your brain and body. They’re responsible for everything you think, do, say, and feel. Sensory circuits carry signals from sense receptors to your brain. Motor circuits send commands to your muscles. Simple circuits carry out your automatic reflexes. Higher-level activities like memory, decision-making, and perceiving the world around you require complex circuits. All of these circuits arise before you’re born, when genes direct neurons to assemble simple circuits in your developing brain. As your neurons and their connections change from new experiences and environments, those simple circuits become much more complex. These changes happen mostly in childhood but continue over your whole life — all a part of building a better brain.
