Download or read book Vertebrate Cranial Placodes written by GERHARD. SCHLOSSER and published by CRC Press. This book was released on 2021-04-29 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the cranial sense organs of vertebrates arise from embryonic structures known as cranial placodes. Such placodes also give rise to sensory neurons that transmit information to the brain as well as to many neurosecretory cells. This book focuses on the development of sensory and neurosecretory cell types from cranial placodes by introducing the vertebrate head with its sense organs and neurosecretory organs and providing an overview of the various cranial placodes and their derivatives, including evidence of common embryonic primordia. Schlosser discusses how these primordia are established in the early embryo and how individual placodes develop. The latter chapters explain how various placodally derived sensory and neurosecretory cell types differentiate into discrete structures.

Download or read book Towards A Semiotic Biology Life Is The Action Of Signs written by Kalevi Kull and published by World Scientific. This book was released on 2011-06-08 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents programmatic texts on biosemiotics, written collectively by world leading scholars in the field (Deacon, Emmeche, Favareau, Hoffmeyer, Kull, Markoš, Pattee, Stjernfelt). In addition, the book includes chapters which focus closely on semiotic case studies (Bruni, Kotov, Maran, Neuman, Turovski).According to the central thesis of biosemiotics, sign processes characterise all living systems and the very nature of life, and their diverse phenomena can be best explained via the dynamics and typology of sign relations. The authors are therefore presenting a deeper view on biological evolution, intentionality of organisms, the role of communication in the living world and the nature of sign systems — all topics which are described in this volume. This has important consequences on the methodology and epistemology of biology and study of life phenomena in general, which the authors aim to help the reader better understand.

Download or read book The Oxford Handbook of Invertebrate Neurobiology written by John H. Byrne and published by Oxford University Press. This book was released on 2019-01-29 with total page 1304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invertebrates have proven to be extremely useful model systems for gaining insights into the neural and molecular mechanisms of sensory processing, motor control and higher functions such as feeding behavior, learning and memory, navigation, and social behavior. A major factor in their enormous contributions to neuroscience is the relative simplicity of invertebrate nervous systems. In addition, some invertebrates, primarily the molluscs, have large cells, which allow analyses to take place at the level of individually identified neurons. Individual neurons can be surgically removed and assayed for expression of membrane channels, levels of second messengers, protein phosphorylation, and RNA and protein synthesis. Moreover, peptides and nucleotides can be injected into individual neurons. Other invertebrate model systems such as Drosophila and Caenorhabditis elegans offer tremendous advantages for obtaining insights into the neuronal bases of behavior through the application of genetic approaches. The Oxford Handbook of Invertebrate Neurobiology reviews the many neurobiological principles that have emerged from invertebrate analyses, such as motor pattern generation, mechanisms of synaptic transmission, and learning and memory. It also covers general features of the neurobiology of invertebrate circadian rhythms, development, and regeneration and reproduction. Some neurobiological phenomena are species-specific and diverse, especially in the domain of the neuronal control of locomotion and camouflage. Thus, separate chapters are provided on the control of swimming in annelids, crustaea and molluscs, locomotion in hexapods, and camouflage in cephalopods. Unique features of the handbook include chapters that review social behavior and intentionality in invertebrates. A chapter is devoted to summarizing past contributions of invertebrates to the understanding of nervous systems and identifying areas for future studies that will continue to advance that understanding.

Download or read book Evolutionary Developmental Biology of Invertebrates 3 written by Andreas Wanninger and published by Springer. This book was released on 2015-08-10 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-author, six-volume work summarizes our current knowledge on the developmental biology of all major invertebrate animal phyla. The main aspects of cleavage, embryogenesis, organogenesis and gene expression are discussed in an evolutionary framework. Each chapter presents an in-depth yet concise overview of both classical and recent literature, supplemented by numerous color illustrations and micrographs of a given animal group. The largely taxon-based chapters are supplemented by essays on topical aspects relevant to modern-day EvoDevo research such as regeneration, embryos in the fossil record, homology in the age of genomics and the role of EvoDevo in the context of reconstructing evolutionary and phylogenetic scenarios. A list of open questions at the end of each chapter may serve as a source of inspiration for the next generation of EvoDevo scientists. Evolutionary Developmental Biology of Invertebrates is a must-have for any scientist, teacher or student interested in developmental and evolutionary biology as well as in general invertebrate zoology. This is the first of three volumes dedicated to animals that molt in the course of their lifecycle, the Ecdysozoa. It covers all non-hexapods and non-crustaceans, i.e., the Cycloneuralia, Tardigrada, Onychophora, Chelicerata and Myriapoda. While the Nematoda and all other phyla are treated in their own chapters, the remaining cycloneuralians are presented jointly due to the dearth of available developmental data on its individual subclades.

Download or read book Development and Neurobiology of Drosophila written by O. Siddiqi and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is no multicellular animal whose genetics is so well understood as Drosophila melanogaster. An increasing number of biologists have, therefore, turned to the fruitfly in pursuit of such diverse areas as the molecular biology of eukaryotic cells, development and neurobiology. Indeed there are signs that Dro sophila may soon become the most central organism in biqlogy for genetic analysis of complex problems. The papers in this collection were presented at a conference on Development and Behavior of Drosophila held at the Tata Insti tute of Fundamental Research from 19th to 22nd December, 1979. The volume reflects the commonly shared belief of the participants that Drosophila has as much to contribute to biology in the future as it has in the past. We hope it will be of interest not merely to Dro sophilists but to all biologists. We thank Chetan Premani, Anil Gupta, K.S. Krishnan, Veronica Rodrigues, Hemant Chikermane and K. Vijay Raghavan for help with recording and transcription of the proceedings and Vrinda Nabar and K.V. Hareesh for editorial assistance. We thank Samuel Richman, Thomas Schmidt-Glenewinkel and T.R. Venkatesh for their valuable assistance in proofreading the manuscripts, and we also thank Patricia Rank for her excellent effort in the preparation of the final manuscripts. The conference was supported by a grant from Sir Dorabji Tata Trust.

Download or read book Adaptive Mechanisms in the Ecology of Vision written by S. Archer and published by Springer Science & Business Media. This book was released on 1999-01-31 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of the ecology of vision has grown considerably since John Lythgoe first wrote his original book on the subject in 1979. John Lythgoe was instrumental in founding the subject that has inspired vision researchers to relate the functioning of the visual system with the visual requirements demanded by the environment and behaviour of the animal in it. This book represents a timely and much needed review of the wealth of research that has been carried out in the last twenty years. It deals with theoretical and physical considerations of light and photoreception, practical examples of visual system structure and function and aspects of visual behaviour and communication. Importantly, the book emphasises one of the main themes to have emerged from studies of the ecology of vision: that the visual system is extremely adaptable when confronted with changing environmental and behavioural conditions. Finally, this updated review is a multi-author collection of leading experts currently working in the field of visual ecology, a requirement that reflects the high level of current research activity. The book approaches the visual system from many different areas of biology including neurobiology, sensory biology, cellular biology and behavioural biology. Consequently, the book will be of interest to workers both within and outside the field of vision research and also to undergraduate and graduate students interested in vision.

Download or read book Tumor Organoids written by Shay Soker and published by Humana Press. This book was released on 2017-10-20 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.
