The newly revised SRS Basics of Sleep Guide, second edition has been significantly expanded in both scope and content, including the addition of 10 new chapters authored by esteemed international experts covering all fields of basic and applied sleep research. Each of the original Basics of Sleep Guide chapters has been completely revised by the authors to reflect the ‘state of the art’ in the particular area of sleep. Many of the chapters now include ‘Sleep Pearls’, an invaluable tool for those preparing for specialty exams associated with basic and clinical sleep sciences. The chapters and figures have also been coordinated with the new SRS Slide Sets (v1.1), providing an excellent foundation for a graduate or medical course in sleep medicine or research.
