Know Your Neurons: How to Classify Different Types of Neurons in the Brain’s Forest
Previously, on Know Your Neurons:Chapter 1: The Discovery and Naming of the Neuron Chapter 2: How to Classify Different Types of Neurons, or The Dendrology of the Neuron Forest Scientists have organized the cells that make up the nervous system into two broad groups: neurons, which are the primary signaling cells, and glia, which support neurons in various ways. All these cells are packed into a three-pound organ about the size of both your fists stuck together. Different Types of Neurons (click to enlarge). A model neuron. Before exploring the brain’s cellular diversity, let’s look at a model neuron. Neurons classified by structure. Scientists have classified neurons into four main groups based on differences in shape. Neurons classified by function. Researchers also categorize neurons by function. Do these basic classes account for all types of neurons? So how many different types of neurons have scientists named so far? And that’s just one region of the brain. References Costandi, M.
