This detailed volume explores olfactory receptors, a topic that goes beyond classical biochemical essays and involves methods to investigate the brain areas associated with the perception of odorants. Gathering the strands of many advanced techniques, the book organizes these key methods in order to achieve a unifying comprehension of the olfactory system. Written for 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.
