The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. The brain is made up of many specialized areas that work together: â¢ The cortex is the outermost layer of brain cells. Thinking and voluntary movements begin in the cortex. â¢ The brain stem is between the spinal cord and the rest of the brain. Basic functions like breathing and sleep are controlled here.
