Editorial Article: Serendipitous rediscovery of neuronal cilia uncovers a previously unknown role Once considered a vestigial organelle, primary cilia are now believed to have an important function in the central nervous system 10 Mar 2021 Dr. Jannon L. Fuchs and her team at the Fundamental Neuroscience Laboratories (FunNeuroLabs), UNT While its common knowledge that neurons communicate with each other through an intricate network of axons, dendrites, and synapses, a less-explored aspect of neuronal communication is its sensory response to the surrounding environment. A specialized appendage called primary cilium, found in neurons throughout the brain, is thought to contribute towards rich sensory and signaling systems within neurons. Not too long ago, however, these very cilia were considered to be functionless.
