(You can roll your mouse over the picture of the brain above to find out more about the parts of the brain.). Neurons. Every part of the brainâand the rest of the nervous system, for that matterâcontain neurons (more than 100 billion of them in all). Neurons are nerve cells with some very special properties.
What are neurons? What is the brain made of? The bulk of the brain is made up of structural cells termed glial cells and astrocytes. Lying in amongst these cells are neurons, specialized cells that conduct electrical impulses along their processes. It has been estimated that the average human brain contains about 100 billion neurons and, on average, each neuron is connected to 1000 other neurons. This results in the generation of vast and complex neural networks that are the mainstay of the brain's processing capabilities.
