This volume discusses the latest approaches used to investigate molecular biology and physiology in the peripheral and central olfactory system. Understanding both normal function and pathobiology provides readers with insight into understanding human olfactory disorders. The chapters in this book cover topics such as techniques for manipulating and measuring olfactory cilia function; approaches for investigating spatial RNA expression in olfactory mucosa; the use of chromatin immunoprecipitation with olfactory neurons; in vivo methods to label and identify activated olfactory neurons; defining organization in the olfactory bulbs and cortex; and the use of optical recording in the mouse olfactory bulb for acute or chronic experiments. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and cutting-edge, The Olfactory System: Methods and Protocols is a valuable resource for all researchers who are interested in learning more about this important and developing field.
