The Pain System

Pain is a subject of significant scientific and clinical interest. This has resulted both from realistic rodent models, and the publication of imaging, psychological and pharmacological studies in humans. Investigators studying rodents refer to anatomical and physiological studies in non-human primates to make their results relevant to humans. Psychophysical and pharmacological studies in humans are interpreted in terms of anatomical and physiological studies in animals; primarily evidence from rodents and cats. There are significant differences in pain mechanisms between these species and primates. Over 20 years of imaging studies have demonstrated the activation of human cortical and subcortical structures in response to painful stimuli. Interpretation of these results relies upon an understanding of the anatomy and physiology of these structures in primates. Jones, Lenz, Casey and Willis review the anatomy and physiology of nociception in monkeys and humans, and provide a firm basis for interpreting studies in humans.

Introduction to Pain and its relation to Nervous System Disorders provides an accessible overview of the latest developments in the science underpinning pain research, including, but not limited to, the physiological, pathological and psychological aspects. This unique book fills a gap in current literature by focussing on the intricate relationship between pain and human nervous system disorders such as Autism, Alzheimer Disease, Parkinson’s Disease, Depression and Multiple Sclerosis. This fully illustrated, colour handbook will help non-experts, including advanced undergraduate and new postgraduate students, become familiar with the current, wide-ranging areas of research that cover every aspect of the field from chronic and inflammatory pain to neuropathic pain and biopsychosocial models of pain, functional imaging and genetics. Contributions from leading experts in neuroscience and psychiatry provide both factual information and critical points of view on their approach and the theoretical framework behind their choices. An appreciation of the strengths and weaknesses of brain imaging technology applied to pain research in humans provides the tools required to understand current cutting edge literature on the topic. Chapters covering placebo effects in analgesia and the psychology of pain give a thorough overview of cognitive, psychological and social influences on pain perception. Sections exploring pain in the lifecycle and in relation to nervous system disorders take particular relevance from a clinical point of view. Furthermore, an intellectually stimulating chapter analysing the co-morbidity of pain and depression provides a philosophical angle rarely presented in related handbooks. The references to external research databases and relevant websites aim to prompt readers to become critical and independent thinkers, and motivate them to carry out further reading on these topics. Introduction to Pain and its relation to Nervous System Disorders is essential reading for advanced undergraduate and postgraduate students in neuroscience, medical and biomedical sciences, as well as for clinical and medical healthcare professionals involved in pain management.

Painâ€"it is the most common complaint presented to physicians. Yet pain is subjectiveâ€"it cannot be measured directly and is difficult to validate. Evaluating claims based on pain poses major problems for the Social Security Administration (SSA) and other disability insurers. This volume covers the epidemiology and physiology of pain; psychosocial contributions to pain and illness behavior; promising ways of assessing and measuring chronic pain and dysfunction; clinical aspects of prevention, diagnosis, treatment, and rehabilitation; and how the SSA's benefit structure and administrative procedures may affect pain complaints.

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

This volume represents edited material that was presented at a conference on brainstem modulation of spinal nociception held in Beaune, France during July, 1987. Pain Modulation, Volume 77 in the series Progress in Brain Research reviews, analyses and suggests new research strategies on several relevant topics including: the endogenous opioid peptides; sites of action of opiates; the role of biogenic animes and non-opioid peptides in analgesia; dorsal horn circuitry; behavioural factors in the activation of pain modulating networks and clinical studies of nociceptive modulation.

This textbook provides an overview of pain management useful to specialists as well as non-specialists, surgeons, and nursing staff.
