The brain consists of an estimated 100 billion neurons. Each neuron can have thousands of connections to other neurons. Also, there are an estimated 10 times the number of glial cells (support cells) as there are neurons. In other words, the brain's communication system is complex. In your discussion post, address each of the following questions:

• How is the brain's complex network of neurons key to the brain-behavior relationship?
• What is the cellular process of information transfer within the brain? Discuss.
• What is the process of information transfer between the brain and the body? Discuss.
• What types of developmental problems could result from childhood disruption of neural systems? Consider emotional, cognitive, or physical problems.
