The human brain is one of the most complex structures in the known universe. Although it makes up only about 2% of your body weight, it consumes roughly 20% of your body's energy to keep billions of nerve cells communicating. Your brain never truly switches off—it remains active while you sleep, helping to regulate breathing, heartbeat, memory formation, and emotional processing. Every second, billions of electrical and chemical signals travel through its vast network of neurons, allowing you to think, learn, create, and adapt. Scientists continue to discover new insights about the brain, proving that this remarkable organ still holds many fascinating mysteries waiting to be understood.
