# Neurons: The Building Blocks of the Brain and How They Shape Our Thoughts, Actions, and Health Neurons are the fundamental units of the human nervous system, responsible for transmitting information throughout the body and brain. As mesmerizing as they are complex, neurons play a vital role in everything from basic reflexes to higher cognitive functions like memory, emotion, and decision-making. Whether you're a neuroscience student, a health enthusiast, or just curious about how your brain works, understanding neurons can unlock a deeper appreciation of what makes us human. ### What Are Neurons? Neurons, or nerve cells, are specialized cells designed to communicate via electrical and chemical signals. Unlike most other cells in the body, neurons do not divide after development—they are primarily excitable and conductive but non-replicating. Their main job is to receive, process, and transmit signals across vast networks to enable perception, behavior, and bodily functions.
