Equine Neurology

• Offers a complete clinical reference to neurologic conditions in equine patients
• Takes a problem-based approach to present a clinically oriented perspective
• Presents new chapters on imaging the nervous system, neuronal physiology, sleep disorders, head shaking, differential diagnosis of muscle trembling and weakness, and cervical articular process joint disease
• Covers the basic principles of neurology, clinical topics such as the initial exam, differentials, and neuropathology, and specific conditions and disorders
• Includes access to a companion website offering video clips demonstrating presenting signs
