Download or read book Electroreceptors and Other Specialized Receptors in Lower Vertrebrates written by T.H. Bullock and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: The originality of this volume is to reveal to the reader the fascination of some unfamiliar sensory organs that are sometimes ignored and often misunderstood. These receptors have only recently been identified and their functional specificity is in some cases still a matter for discussion. The four classes of sensory organs considered here differ widely from one another in many respects. One might even say that the only thing they have in common is that they belong to cold-blooded vertebrates. These classes are: 1. the directionally sensitive lateral-line mechanoreceptors of fishes and amphi bians (Chapter 7); 2. the pseudobranchial organs of some teleosts, equipped with pressoreceptors and at least three other types of receptors (osmo- and chemoreceptors) (Chapter 8); 3. the infrared-sensitive pit organs of some snake families (Chapter 9) ; 4. the various kinds of electroreceptors found in several marine and freshwater fish families (Chapters 2 to 6). The first three classes of receptors mentioned above thus rate only one chapter each, whereas five chapters are devoted to the electroreceptors. Electroreception has aroused enormous interest among physiologists in specialties ranging from molecular biology to animal behavior. The resulting quantity of research and discussion fully justifies this disproportion. However, it cannot be denied that the contents of the volume must appear unbalanced and heterogeneous, yet it should not be perceived as a mere juxtaposition of particular and unrelated cases.

Book Synopsis Mechanistic Approaches to Interactions of Electric and Electromagnetic Fields with Living Systems by : Martin Blank
Download or read book Mechanistic Approaches to Interactions of Electric and Electromagnetic Fields with Living Systems written by Martin Blank and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there is general agreement that exogenous electric and electromagnetic fields influence and modulate the properties of biological systems. there is no concensus regarding the mechanisms by which such fields operate. It is the purpose of this volume to bring together and examine critically the mechanistic models and concepts that have been proposed. We have chosen to arrange the papers in terms of the level of biological organization emphasized by the contributors. Some papers overlap categories. but the progression from ions and membrane surfaces. through macromolecules and the membrane matrix to integrated systems. establishes a mechanistic chain of causality that links the basic interactions in the relatively well understood simple systems to the complex living systems. where all effects occur simultaneously. The backgrounds of the invited contributors include biochemistry. biophysics. cell biology. electrical engineering. electrochemistry. electrophysiology. medicine and physical chemistry. As a result of this diversity. the mechanistic models reflect the differing approaches used by these disciplines to explain the same phenomena. Areas of agreement define the common ground. while the areas of divergence provide opportunities for refining our ideas through further experimentation. To facilitate the interaction between the different points of view, the authors have clearly indicated those published observations that they are trying to explain. i.e. the experiments that have been critical in their thinking. This should establish a concensus regarding important observations. In the discussion of theories.

Book Synopsis CRC Handbook of Biological Effects of Electromagnetic Fields by : Charles Polk
Download or read book CRC Handbook of Biological Effects of Electromagnetic Fields written by Charles Polk and published by CRC Press. This book was released on 2019-07-23 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to present in a concise manner what is actually known at the present time about biological effects of time invariant, low frequency and radio frequency (including microwave) electric and magnetic fields. In reviewing the vast amount of experimental data which have been obtained in recent years, the authors tried to select those results that are, in their opinion, of major importance and of lasting value. In discussing mechanisms of interaction of electromagnetic fields with living matter they have tried to differentiate between what is clearly established, what is suggested by available evidence without being convincingly proven, and what is conjecture at the present time.

Book Synopsis Sensory Mechanisms of the Spinal Cord by : W. D. Willis
Download or read book Sensory Mechanisms of the Spinal Cord written by W. D. Willis and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this monograph is to provide an overview of current thought about spinal cord mechanisms for sensory processing. We hope that the book will be useful both to basic neuroscientists and to clinicians. So me historical aspects of the problem and a few definitions are treated in the first chapter. The second chapter reviews the organiza tion of the peripheral nervous system from the standpoint of sensory receptors and primary afferent axons. The third chapter is concerned with what is known about the structure of the dorsal horn, while the fourth chapter considers the activity of dorsal horn interneurons. The clinical, behavioral, and neurophysiological evidence for what parts of the cord white matter contain particular sensory pathways is discussed in Chapter 5, and details about the various pathways in the dorsal columns, the dorsolateral fasciculus, and the ventral quadrant form the . subject matter of Chapters 6 through 8. The final chapter is an attempt to summarize what is presently known about the receptors and the spinal cord pathways responsible for the sensations of touch-pressure, flutter-vibration, pain, temperature, position sense and visceral sensa tion and about descending control systems.

Available in PDF, EPUB and Kindle. Book excerpt: I fancy that many of you, like myself, have woken up in the night with a "sleeping" arm or leg. It is a very peculiar feeling to have that arm or leg, cold and lifeless, hanging there at your side as if it were something which does not belong to you. In such situations you recover some of the motor functions before the sensory functions, which en ables you to move the limb like a pendulum. For a few sec onds the arm functions as an artificial limb - a prosthesis without sensors. In general we are not aware of the importance of our sensory organs until we lose them. You do not feel the pressure of your clothes on the skin or the ring on your finger. In the nineteenth century such phenomena generally named adaptation, were studied to a great extent, partic ularly in vision, as well as in the so-called lower senses. The question whether sensory adaptation was due to changes in the peripheral sensory receptors or in the central nervous structure remained in general open until the 1920s. Then the development of the electronic arsenal gave us the means to attack the problem by direct observations of the electrical events in the peripheral as well as the central nervous system. But even today there are still some blank areas in our knowledge of adaptation.
Book Synopsis Foundations of Sensory Science by : H. Autrum
Download or read book Foundations of Sensory Science written by H. Autrum and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: When seen from an outsider's vantage point, the development of knowledge in the sensory sciences must appear massive and the result of some carefully followed master plan. In reality, it is the result of numerous relatively independent human endeavors shaped by application of the scientific method. The comprehensive construction of quantitative theories of sense organ function has occurred only recently -but at an explosive rate prefaced by centuries of expansion in the physical sciences. Predicated on this growth, the twentieth century may become known as the age of the biological sciences. With the exception of a modest number of intellectual giants, there were few contributors to the foundations of the sensory sciences before the dawn of this century. At least 90% of existing knowledge has been produced by scientists working in laboratories founded since 1920. If any single scientist and his laboratory may be identified with the growth in the sensory sciences, it is EDGAR DOUGLAS ADRIAN, First Baron of Cambridge and leader of the Physiological Laboratory at Cambridge University, England. Lord ADRIAN'S influence upon the sensory sciences was great, not only in terms of his contribution to knowledge itself but also through the influence which he exerted upon numerous young scientists who spent weeks or years at the Cambridge laboratory and who later returned to their homelands and colleagues with the seeds of vigorous research and quantitative inquiry firmly implanted.

This book was released on 2013-06-29 with total page 1016 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third edition of this monograph continues to have the goal of providing an overview of current thought about the spinal cord mechanisms that are responsible for sensory processing. We hope that the book is of value to both basic and clinical neuroscientists. Several changes have been made in the presentation, as well as additions because of the research advances that have been made during the past decade. Chapters 3 and 4 in the previous edition have been subdivided, and now the morphology of primary afferent neu rons of the dorsal root ganglia is described in Chapter 3 and the chemical neuroanatomy of these neurons in Chapter 4. The description of the dorsal horn in the previous Chapter 4 is now included in Chapter 5, and the chemical neuroanatomy of the dorsal horn in Chapter 6. Furthermore, discussions of the descending control systems have now been consolidated at the end of Chapter 12. The authors would like to express their appreciation for the help provided by several individuals. R.E.C. wishes to acknowledge the many things he learned about primary afferent neurons from conversations with Dr S. N. Lawson. He also thanks Lyn Shilling for her assistance with the typing. WDW thanks Dr Nada Lawand for her critical reading of parts of the manuscript, Rosaline Leigh for help with the manuscript, and Griselda Gonzales for preparing the illustrations.
Download or read book The Paraneuron written by Tsuneo Fujita and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The regulation of the organism has traditionally been ascribed to two distinct systems-the nervous and the endocrine. Though coordination between the two systems has been acknowledged, researchers and authors have tended to deal with them as comprising separate categories of cells involved in different activities. With this approach, a given regulatory mechanism would be evaluated as to whether it should be accounted for by nervous or endocrine functions. The past 15 years, however, have witnessed numerous important discoveries and conceptual developments concerning the morphological, physiological, and bio chemical relations between the nervous and endocrine systems. Advances in im munocytochemical studies have revealed that there are a wide variety of messenger substances that function in both regulatory systems. As a result, researchers have been stimulated to investigate neuronlike properties of endocrine cells and, con versely, endocrine or secretory features of neurons. It has thus become obvious that the rigidities in the classic criteria of neurotransmitters and hormones may rather impede further advances in these research fields. The activities of neurons are no longer evaluated simply in terms of EPSP, IPSP, and the release of classic trans mitters such as acetylcholine, noradrenaline, and GABA. Hormonal actions are no longer analyzed solely with regard to concentrations of classic aminic and peptidic hormones in the systemic blood circulation. The concept of the paraneuron, which we proposed in 1975, has become one of the theoretical bases for the development of this trend of study.

Download or read book Inside the Photon written by Tony Fleming and published by CRC Press. This book was released on 2014-03-20 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade biophotonics has appeared as a new department within the academic structure across the globe. With experimental work going back for more than a century, application of the scientific method has shown the importance of biophotonics within biological and medical practice. At the same time, a new mathematical description of physics and biophysics has emerged. Self-Field Theory (SFT) describes the role of photon as a binding agent between an electron and a proton within atomic structures. SFT is being rapidly accepted by the physics community as a distinct physical theory. This is now an alternative view, in addition to classical electromagnetics and the quantum theories, that forms the basis of a chemical bond. Atomic chemistry underpins biochemistry, the pharmaceutical approach to medical therapy, and has been a staple of biological and medical knowledge over the 20th century. The biophoton within SFT provides another layer of structural organization that sits underneath atomic chemistry. This book is the first to describe SFTs role within biophotonics and as such provides a theory of biophotonics capable of describing a wide range of experimental biophotonic phenomena. Inside the Photon: A Journey towards Health describes the newly discovered layer of biophotonics underlying all atomic chemistry and biochemistry. As with the variety of snowflakes, the range in biological species within flora for instance is dependent on this biophotonic layer of interaction within atomic and biomolecular structures. A new range of energies that can be balanced only within the biophotonic states are responsible for these innumerable varieties of biological species. The phonon, the quantum of acoustic, or vibrational, energy is also described and given status alongside the photon. Hence the ‘biophonon’ sits aside the biophoton as an element within biological structures. Sounds can create structure in the same way biophotons can use structure to communicate. Therapies such as homeopathy, acupuncture, traditional Chinese medicines are given fresh impetus including putative understanding of mechanism. Mitosis is understood via the cell cycle and how electric, acoustic, and magnetic fields can induce changes at the biophotonic level. The possibility arises of medical therapy without invasive surgery and without the side effects of drug-based therapies.
