The brain is made up of an estimated 100 billion neurons, and each neuron can have thousands of connections to other neurons. Additionally, there are an estimated 10 times the number of glial cells (support cells) as there are neurons, lending to an extremely complex system of communication in the brain. How is this complex network of neurons in the brain key to the brain-behavior relationship? Discuss the process of information transfer within the brain and between the brain and the body. What types of developmental problems (emotional, cognitive, or physical) do you think could result from disruption of neural systems during childhood?
