In Motor Activity and Movement Disorders thirteen state-of-the-art articles explicate forefront research methodologies for measuring and interpreting motor activity in animals, as well as their applications to preclinical and clinical research involving motor disorders. The contributors emphasize motor asymmetries, turning behavior, and dyskinetic movements. They also present a variety of quantitative approaches designed to assess specific aspects of motor activity and illustrate numerous computerized measuring techniques that permit detailed and objective approaches to quantifying motor behavior. Motor Activity and Movement Disorders will contribute to a greater understanding of brain-behavior relationships through its focus on methodology and its application to current animal models and to human disorders.
