Download Neuroglia in C. elegans Book in PDF, ePub and Kindle
The nematode C. elegans is one of the most important model organisms for understanding neurobiology. Its completely mapped neural connectome of 302 neurons and fully characterized and stereotyped development have made it a prototype for understanding nervous system structure, development, and function. Fifty-six out of C. elegans' total of 959 somatic cells are classified as neuroglia. Although research on worm glia has lagged behind studies focused on neurons, there has been a steep upswing in interest during the past decade. Information arising from the recent burst of research on worm glia supports the idea that C. elegans will continue to be an important animal model for understanding glial cell biology. Since the developmental lineage of all cells was mapped, each glial cell in C. elegans is known by a specific name and has research associated with it. We list and describe the glia of the hermaphrodite form of C. elegans and summarize research findings relating to each glial cell. We hope this lecture provides an informative overview of worm glia to accompany the excellent and freely available online resources available to the worm research community.

Download The Neurobiology of C. elegans Book in PDF, ePub and Kindle
The Neurobiology of C. elegans assembles together a series of chapters describing the progress researchers have made toward solving some of the major problems in neurobiology with the use of this powerful model organism. The first chapter is an introduction to the anatomy of the C. elegans nervous system. This chapter provides a useful introduction to this system and will help the reader who is less familiar with this system understand the chapters that follow. The next two chapters on learning, conditioning and memory and neuronal specification and differentiation, summarize the current state of the C. elegans field in these two major areas of neurobiology. The remaining chapters describe studies in C. elegans that have provided particularly exciting insights into neurobiology.

Download Ay's Neuroanatomy of C. Elegans for Computation Book in PDF, ePub and Kindle
First published in 1992, AY's Neuroanatomy of C. elegans for Computation provides the neural circuitry database of the nematode Caenorhabditis elegans, both in printed form and in ASCII files on 5.25-inch diskettes (for use on IBM® and compatible personal computers, Macintosh® computers, and higher level machines). Tables of connections among neuron classes, synapses among individual neurons, gap junctions among neurons, worm cells and their embryonic origin, and synthetically derived neuromuscular connections are presented together with the references from which the data were compiled and edited. Sample data files and source codes of FORTRAN and BASIC programs are provided to illustrate the use of mathematical tools for any researcher or student interested in examining a natural neural network and discovering what makes it tick.

Download Genomic Regulatory Systems Book in PDF, ePub and Kindle
The interaction between biology and evolution has been the subject of great interest in recent years. Because evolution is such a highly debated topic, a biologically oriented discussion will appeal not only to scientists and biologists but also to the interested lay person. This topic will always be a subject of controversy and therefore any breaking information regarding it is of great interest.The author is a recognized expert in the field of developmental biology and has been instrumental in elucidating the relationship between biology and evolution. The study of evolution is of interest to many different kinds of people and Genomic Regulatory Systems: In Development and Evolution is written at a level that is very easy to read and understand even for the nonscientist. * Contents Include* Regulatory Hardwiring: A Brief Overview of the Genomic Control Apparatus and Its Causal Role in Development and Evolution * Inside the Cis-Regulatory Module: Control Logic and How the Regulatory Environment Is Transduced into Spatial Patterns of Gene Expression* Regulation of Direct Cell-Type Specification in Early Development* The Secret of the Bilaterians: Abstract Regulatory Design in Building Adult Body Parts* Changes That Make New Forms: Gene Regulatory Systems and the Evolution of Body Plans

Download Monoamines, Mechanosensation and Memory in the C. Elegans Nervous System Book in PDF, ePub and Kindle
One of the main goals of neurobiology, and the focus of this dissertation, is to understand how genes act within a nervous system to generate behavior. The nematode Caenorhabditis elegans has a relatively simple nervous system comprised of 302 neurons with known connectivity. Despite this simplicity, C. elegans displays a wide-range of behaviors with surprising complexity. Well-developed genetics combined with a manageable nervous system make C. elegans a useful model to study how genes alter behavior. This dissertation focuses on the mechanosensory neurons of C. elegans. In the development of the gentle touch mechanosensory neurons, serotonin appears to act as permissive cue that allows these neurons to migrate to their proper locations. Mutations in Go-alpha (goa-1) signaling and the calcium channel (unc-2) also affect migration of the gentle touch neurons. Genetic analysis confirms that these genes act in the same pathway to confer motility to the migrating touch neurons. Dopamine is also important for the gentle touch neurons, but not developmentally. DOP-1, a D1-like dopamine receptor expressed in the touch neurons, is required for normal habituation of the gentle touch response. Cell-specific rescue confirms a role for DOP-1 signaling in the touch cells during habituation. Further genetic analysis indicates that Gq-alpha (egl-30) signaling couples to DOP-1. This signaling utilizes the second messengers IP3 and DAG to act on ER calcium and PKC activity respectively to modulate habituation. In vivo calcium imaging indicates that this signaling cascade acts cell autonomously to regulate touch cell sensitivity. Food is an essential cue for dopamine modulation of touch habituation; in the absence of food, DOP-1 worms habituate at the same rate as wildtype. Experiments also suggest that worms utilize their dopamine neurons to sense food mechanically, and release dopamine to slow habituation; this is dependent on the TRPN channel TRP-4. Another potential mechanosensitve TRP channel in C. elegans, TRPA-1 was recently identified. This channel is not required for gentle touch, but instead a distinct type of mechanosensation, nose touch and also foraging related behaviors. Cell-specific rescue and in vivo calcium imaging confirmed a direct role for TRPA-1 in nose touch neurons.

Download The Oxford Handbook of Invertebrate Neurobiology Book in PDF, ePub and Kindle
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.
