Normal and Dying Neuron, Alzheimer's Disease
Illustration of normal (left) and dying (right) neurons. The healthy human brain contains tens of billions of neurons that process and transmit information via electrical and chemical signals. Most neurons have three basic components: a cell body, multiple dendrites, and an axon. The cell body contains the nucleus, which houses the genetic blueprint that directs and regulates the cell's activities. Dendrites are branch-like structures that radiate from the cell body and collect information from other neurons. The axon extends from the other end of the cell body and transmits messages to other neurons. While the brain may shrink to some degree in healthy aging, it does not lose neurons in large numbers. In Alzheimer's disease, however, damage is widespread as many neurons stop functioning, lose connections with other neurons, and die.
