In this post, we explore Chapter 3 of Neuroscience for Dummies (3rd Edition) , focusing on how neurons operate, communicate, and contribute to brain function. This foundational chapter breaks down the structure of a neuron, the mechanics of action potentials, the complexity of synaptic signaling, and the essential role of glial cells. Whether you're studying neurobiology, psychology, or medicine, this summary will clarify one of the most important topics in neuroscience. What Are Neurons and How Do They Work? Neurons are the building blocks of the nervous system. Each neuron consists of dendrites (which receive input), a cell body (which integrates the signals), and an axon (which sends output to other neurons). Information is transmitted via action potentials , electrical ...
