Though we weren’t aware of it, our brain was growing explosively in the first few years of our lives. From birth to age three, babies gain more than a million neural connections every second. This crucial period of brain formation will affect how a person learns, communicates and behaves for the rest of their lives.
The brain is made up of neurons, specialized cells that send messages to the rest of the body. Every new experience and memory creates connections between neurons, or synapses. These connections enable basic brain functions.
