Our human brains are amazing. This complex organ is our command center. The function of our cognitive, sensory, social, emotional, behavioral, and learned skills relies on our brain health. White matter, grey matter, blood vessels, and nerves—the human brain is about 60 percent fat. The remaining 40 percent is a combination of water, protein, carbohydrates, and salts. Our brain weighs in at about 3 pounds, with an incredible 86 billion neurons. Our neurons, or nerve cells, communicate constantly with each other by releasing chemical messengers called neurotransmitters.
And, through a process known as neurogenesis, our incredibly adaptive brains can grow new brain cells. Our ability to change our minds extends well past midlife. We can learn new things, acquire new skills, and recover from brain injury throughout our lives….
