Generation of Genetic Tools by Gene Expression Intersection for Manipulating Neuronal Circuits in the Drosophila Brain
Author: 江孟軒Decoding Neural Circuit Structure and Function

Pages : 517
Book Description
This book offers representative examples from fly and mouse models to illustrate the ongoing success of the synergistic, state-of-the-art strategy, focusing on the ways it enhances our understanding of sensory processing. The authors focus on sensory systems (vision, olfaction), which are particularly powerful models for probing the development, connectivity, and function of neural circuits, to answer this question: How do individual nerve cells functionally cooperate to guide behavioral responses? Two genetically tractable species, mice and flies, together significantly further our understanding of these processes. Current efforts focus on integrating knowledge gained from three interrelated fields of research: (1) understanding how the fates of different cell types are specified during development, (2) revealing the synaptic connections between identified cell types (“connectomics”) using high-resolution three-dimensional circuit anatomy, and (3) causal testing of how iden tified circuit elements contribute to visual perception and behavior.

Book Description
We demonstrate the feasibility of generating thousands of transgenic Drosophila melanogaster lines in which the expression of an exogenous gene is reproducibly directed to distinct small subsets of cells in the adult brain. We expect the expression patterns produced by the collection of 5,000 lines that we are currently generating to encompass all neurons in the brain in a variety of intersecting patterns. Overlapping 3-kb DNA fragments from the flanking noncoding and intronic regions of genes thought to have patterned expression in the adult brain were inserted into a defined genomic location by site-specific recombination. These fragments were then assayed for their ability to function as transcriptional enhancers in conjunction with a synthetic core promoter designed to work with a wide variety of enhancer types. An analysis of 44 fragments from four genes found that>80% drive expression patterns in the brain; the observed patterns were, on average, comprised of 100 cells. Our results suggest that the D. melanogaster genome contains50,000 enhancers and that multiple enhancers drive distinct subsets of expression of a gene in each tissue and developmental stage. We expect that these lines will be valuable tools for neuroanatomy as well as for the elucidation of neuronal circuits and information flow in the fly brain.
Genetic Manipulation of the Nervous System

ISBN: 0080532403
Category : Science

Pages : 297
Book Description
Neuroscience Perspectives provides multidisciplinary reviews of topics in one of the most diverse and rapidly advancing fields in the life sciences. Whether you are a new recruit to neuroscience, or an established expert, look to this series for 'one-stop' sources of the historical, physiological, pharmacological, biochemical, molecular biological and therapeutic aspects of chosen research areas. The recent development of Gene Therapy procedures which allow specific genes to be delivered to human patients who lack functional copies of them is of major therapeutic importance. In addition such gene delivery methods can be used in other organisms to define the function of particular genes. These studies are of particular interest in the nervous system where there are many incurable diseases like Alzheimer's and Parkinson's diseases which may benefit from therapies of this kind. Unfortunately gene delivery methods for use in the nervous system have lagged behind those in other systems due to the fact that the methods developed in other systems are often not applicable to cells like neurons which do not divide. This book discusses a wide range of methods which have now been developed to overcome these problems and allow safe and efficient delivery of particular genes to the brain. Methods discussed include virological methods, physical methods (such as liposomes) and the transplantation of genetically modified cells. In a single volume therefore this book provides a complete view of these methods and indicates how they can be applied to the development of therapies for treating previously incurable neurological disorders.
Controlled Genetic Manipulations
Author: Alexei MorozovPublisher: Humana Press
ISBN: 9781493961962
Category : Medical
Languages : en
Pages : 227
Book Description
The current demand for the development of techniques for controlled genetic manipulations is driven by the anatomical and physiological complexity of the brain and by the need for experimental models that can address this complexity through selective manipulation of defined components of the system: specific neuronal populations or selected synapses. In Controlled Genetic Manipulations, expert researchers present detailed chapters to supply basic technical information about controlled genetic manipulations and to provide examples of creative implementation of this methodology when addressing a unique biological problem. Some chapters of the book describe the most recent developments in the basic methodology, which includes use of Cre-recombinase, methods for delivery of genetic material into the brain and the use of optogenetics, whereas other chapters focus on applying these techniques to addressing particular biological questions like structural and functional mapping of neuronal circuits, analysis of specific synaptic connections, modeling or gene therapy of neurological disorders. As part of the Neuromethods series, chapters include key implementation advice that is crucial for getting optimal results. Authoritative and practical, Controlled Genetic Manipulations serves as a valuable guide to a variety of techniques, provided by many of the pioneers of the approaches.
Design Thinking in Consulting
Author: Mohan KancharlaPublisher: Notion Press
ISBN: 1637816383
Category : Business & Economics
Languages : en
Pages : 242
Book Description
Consulting is an Art, not a Science – Design on the other hand is beyond Art; it’s about pragmatic compromise, not perfection. Design Thinking in literal terms means thinking as a designer would. Design Thinking as a method is empirical in the sense that it is both experimental and experiential. However, like all methods, it’s not what it is but what you do with it that counts! Design Thinking is an approach to innovation that is powerful, effective and broadly accessible, which can be integrated into all aspects of products, services, business and society. Design Thinking in Consulting is structured in three parts along the lines of Roger Martin’s ‘Knowledge Funnel’ moving from Mystery to Heuristic to Algorithm. Part I | Consulting Overview of Consulting with a specific focus on Consulting Spectrum and Consulting Cycle for the purpose of this book – The Mystery. Part II | Design Thinking Introduction to Design Thinking, the various schools of thought, approaches, tools and techniques analyzed and articulated as a matrix of Principles vs Practices for the purpose of this book – The Heuristic. Part III | Design Thinking in Consulting In separate chapters for each of the Consulting Phases, the above Design Thinking Principles and Practices are evaluated to be fit for purpose and further extrapolated to relevant segments of the Consulting Spectrum for the purpose of this book – The Algorithm.
Drosophila Eye Development

Book Description
1 Kevin Moses It is now 25 years since the study of the development of the compound eye in Drosophila really began with a classic paper (Ready et al. 1976). In 1864, August Weismann published a monograph on the development of Diptera and included some beautiful drawings of the developing imaginal discs (Weismann 1864). One of these is the first description of the third instar eye disc in which Weismann drew a vertical line separating a posterior domain that included a regular pattern of clustered cells from an anterior domain without such a pattern. Weismann suggested that these clusters were the precursors of the adult ommatidia and that the line marks the anterior edge of the eye. In his first suggestion he was absolutely correct - in his second he was wrong. The vertical line shown was not the anterior edge of the eye, but the anterior edge of a moving wave of patterning and cell type specification that 112 years later (1976) Ready, Hansen and Benzer would name the "morphogenetic furrow". While it is too late to hear from August Weismann, it is a particular pleasure to be able to include a chapter in this Volume from the first author of that 1976 paper: Don Ready! These past 25 years have seen an astonishing explosion in the study of the fly eye (see Fig.

Book Description
The small fruit fly, Drosophila melanogaster, has for over a century now had a large impact on biological and biomedical research; however, our knowledge of the fly brain has lagged significantly behind our understanding of other aspects of its development, physiology, and function. In The Making and Un-Making of Neuronal Circuits in Drosophila, innovative expert neuroscientists in the field present the ideas and concepts behind the methods, tools, and tricks that are currently being utilized to decode the secrets of this valuable insect’s brain. Focused on the concept of a neuronal circuit, defined as a series of synaptically connected neurons subservient to a particular behavioral modality, this volume contains chapters dealing with anatomical analysis with a focus on cellular and sub-cellular morphologies. These detailed approaches fall under the headings of “Physiology” and “Behavior”, conveniently divided the book into two sections. Written in the easy-to-follow Neuromethods series format, this work provides the kind of detailed description and implementation advice that is crucial for getting optimal results. Inventive and accessible, The Making and Un-Making of Neuronal Circuits in Drosophila provides the information and tools necessary to carry out current experiments and, more importantly, further advance the progress of the Drosophila neurobiology field and neurobiology in general.

Book Description
Drosophila is a marvelous system to study the underlying principles that govern how neural circuits govern behaviors. The scale of the fly brain (approximately 100,000 neurons) and the complexity of the behaviors the fly can perform make it a tractable experimental model organism. In addition, 100 years and hundreds of labs have contributed to an extensive array of tools and techniques that can be used to dissect the function and organization of the fly nervous system. This review discusses both the conceptual challenges and the specific tools for a neurogenetic approach to circuit mapping in Drosophila.
Innate
Author: Kevin J. MitchellPublisher: Princeton University Press
ISBN: 0691204152
Category : Psychology
Languages : en
Pages : 305
Book Description
"What makes you the way you are--and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains. Deftly guiding us through important new research, including his own groundbreaking work, he explains how variations in the way our brains develop before birth strongly influence our psychology and behavior throughout our lives, shaping our personality, intelligence, sexuality, and even the way we perceive the world. We all share a genetic program for making a human brain, and the program for making a brain like yours is specifically encoded in your DNA. But, as Mitchell explains, the way that program plays out is affected by random processes of development that manifest uniquely in each person, even identical twins. The key insight of Innate is that the combination of these developmental and genetic variations creates innate differences in how our brains are wired--differences that impact all aspects of our psychology--and this insight promises to transform the way we see the interplay of nature and nurture. Innate also explores the genetic and neural underpinnings of disorders such as autism, schizophrenia, and epilepsy, and how our understanding of these conditions is being revolutionized. In addition, the book examines the social and ethical implications of these ideas and of new technologies that may soon offer the means to predict or manipulate human traits. Compelling and original, Innate will change the way you think about why and how we are who we are."--Provided by the publisher.
