"The fourth edition of Quick Reference Neuroscience continues to meet a need in the rehabilitation professions that has gone unfilled-the availability of a source that simplifies and thoroughly breaks down neuroscience information into the essential principles that can be used to understand neurological conditions and principles underlying rehabilitation evaluation and practice. Although many excellent textbooks exist that provide exhaustive neuroscience information, much of that information may be extraneous to a practicing therapist who needs to quickly review a specific neuroscience concept to better explain that information to a patient, or it may be extraneous to a student needing to learn the critical neuroscience principles supporting a specific rehabilitation intervention. We are all on information overload and need resources that quickly but fully provide condensed information in a user-friendly, easy-to-use format. The discipline of neuroscience has exploded in the past 2 decades as imaging technologically has facilitated knowledge of the brain in ways previously unimaginable. Much of this newly gained knowledge of brain function relates to molecular and cellular levels-levels of brain analysis of which highly competent rehabilitation therapists do not require in-depth understanding. In fact, much of the molecular and cellular understanding of brain function is not directly used by therapists to treat patients in clinical rehabilitation settings. While it is important to have some understanding of the cellular brain processes underlying behavior, our need as rehabilitation professionals to use this information in practice is not the same as that of a neurologist, neurosurgeon, or neuropathologist. Rehabilitation practitioners are under overwhelming productivity demands for patient care and for evidence dissemination (ie, reading journal articles and using relevant research evidence in practice). Students in rehabilitation health care programs are similarly under tremendous pressure to master a large body of relevant coursework and fieldwork education in a limited amount of time. It seems imprudent to further add to student and practitioner requirements the need to memorize cellular neuroscience information that will not be used in practice. New to this edition are examples of occupational performance implications. Occupational performance implications illustrate how neurological dysfunction translates into problems in the participation of daily life activities. Problems in the performance of daily life activities are the primary concern of rehabilitation professionals, whose role it is to help people engage in desired daily life activities despite the presence of illness, disability, or injury. This edition also provides the full screening methods for such things as cranial nerve testing and deep tendon reflex testing"--
