This volume provides researchers with up-to-date protocols and takes a close look at current research and promising applications. Optogenetics: Methods and Protocols contains a collection of recently developed technical protocols on optogenetic applications in neuroscience, brain mapping, treatment of neurological disorders, and restoration of visual function. Several introductory and discussion chapters offer a wide overview about sources and diversity of optogenetic tools, design strategies, and potential applications in other fields like plant research. 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. Cutting edge and thorough, Optogenetic: Methods and Protocols, delivers an interdisciplinary view of optogenetic applications and its potential to develop as a valuable tool for basic research, as well as biomedical and biotechnological applications.
