5. The neuron forest

Brain Basics

05a.jpgThe real work of your brain goes on in individual cells. An adult brain contains about 100 billion nerve cells, or neurons, with branches that connect at more than 100 trillion points. Scientists call this dense, branching network a “neuron forest.”

 

Signals traveling through the neuron forest form the basis of memories, thoughts, and feelings.

Neurons are the chief type of cell destroyed by Alzheimer’s disease.
