Download or read book Electric Brain written by R. Douglas Fields and published by BenBella Books. This book was released on 2020-02-04 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is as unique as your fingerprints and more revealing than your diary? Hint: Your body is emitting them right now and has been every single day of your life. Brainwaves. Analyzing brainwaves, the imperceptible waves of electricity surging across your scalp, has been possible for nearly a century. But only now are neuroscientists becoming aware of the wealth of information brainwaves hold about a person's life, thoughts, and future health. From the moment a reclusive German doctor discovered waves of electricity radiating from the heads of his patients in the 1920s, brainwaves have sparked astonishment and intrigue, yet the significance of the discovery and its momentous implications have been poorly understood. Now, it is clear that these silent broadcasts can actually reveal a stunning wealth of information about any one of us. In Electric Brain, world-renowned neuroscientist and author R. Douglas Fields takes us on an enthralling journey into the world of brainwaves, detailing how new brain science could fundamentally change society, separating fact from hyperbole along the way. In this eye-opening and in-depth look at the most recent findings in brain science, Fields explores groundbreaking research that shows brainwaves can: • Reveal the type of brain you have—its strengths and weaknesses and your aptitude for learning different types of information • Allow scientists to watch your brain learn, glean your intelligence, and even tell how adventurous you are • Expose hidden dysfunctions—including signifiers of mental illness and neurological disorders • Render your thoughts and transmit them to machines and back from machines into your brain • Meld minds by telepathically transmitting information from one brain to another • Enable individuals to rewire their own brains and improve cognitive performance Written by one of the neuroscientists on the cutting edge of brainwave research, Electric Brain tells a fascinating and obscure story of discovery, explains the latest science, and looks to the future—and the exciting possibilities in store for medicine, technology, and our understanding of ourselves.
Download or read book The Brain Electric written by Malcolm Gay and published by Macmillan. This book was released on 2015-10-20 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leading neuroscience researchers are racing to unlock the secrets of the mind. On the cusp of decoding brain signals that govern motor skills, they are developing miraculous technologies that will enable paraplegics and wounded soldiers to move prosthetic limbs and will give all of us the power to manipulate computers and other objects through thought alone. These fiercely competitive scientists are vying for government and venture capital funding, prestige, and wealth. Part life-altering cure, part science fiction, part Defense Department dream, these cutting edge brain-computer interfaces promise to improve lives-but they also hold the potential to augment soldiers' combat capabilities. In The Brain Electric, Malcolm Gay follows the dramatic emergence of these technologies, taking us behind the scenes in operating rooms, startups, and research labs, where the future is unfolding. With access to many of the field's top scientists, Gay illuminates this extraordinary race-where science, medicine, profit, and war converge-for the first time. But this isn't just a story about technology. At the heart of the scientists' research is a group of brave patient-volunteers, whose lives are given new meaning through these experiments. The Brain Electric asks us to rethink our relationship to technology, our bodies, even consciousness itself, challenging our assumptions about what it means to be human.

This book was released on 2022-06-22T22:59:00Z with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Please note: This is a companion version & not the original book. Sample Book Insights: #1 The boy was shot in the head, and the bullet could not be removed by surgery. It left him paralyzed on one side of his body and suffering from vertigo. He was sent to a mental hospital in Jena, Germany, by his doctor, Hans Berger. #2 In November 1902, Berger conducted the experiment with the young man. He shaved the man’s head, and then toweled it dry. He took extra care with the area around the head wound, where the missing skull bone had left an irregularly shaped hole covered only by a thin layer of skin and scar tissue. #3 Dr. Berger was the first to test his theory that mental states interact with physical processes inside the brain. He recorded the young man’s brain pulsations, which were affected by various drugs and changes in body position. #4 Berger was the first person to document waves of electrical energy radiating out from the human skull, and he was also the first to conduct a human electroencephalogram. But he remains a shadowy figure, as the ethically unpalatable practice of experimenting on patients hardly makes him unique among his contemporaries in psychiatry.

Download or read book The Spike written by Mark Humphries and published by Princeton University Press. This book was released on 2023-01-24 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of a neural impulse and what it reveals about how our brains work We see the last cookie in the box and think, can I take that? We reach a hand out. In the 2.1 seconds that this impulse travels through our brain, billions of neurons communicate with one another, sending blips of voltage through our sensory and motor regions. Neuroscientists call these blips “spikes.” Spikes enable us to do everything: talk, eat, run, see, plan, and decide. In The Spike, Mark Humphries takes readers on the epic journey of a spike through a single, brief reaction. In vivid language, Humphries tells the story of what happens in our brain, what we know about spikes, and what we still have left to understand about them. Drawing on decades of research in neuroscience, Humphries explores how spikes are born, how they are transmitted, and how they lead us to action. He dives into previously unanswered mysteries: Why are most neurons silent? What causes neurons to fire spikes spontaneously, without input from other neurons or the outside world? Why do most spikes fail to reach any destination? Humphries presents a new vision of the brain, one where fundamental computations are carried out by spontaneous spikes that predict what will happen in the world, helping us to perceive, decide, and react quickly enough for our survival. Traversing neuroscience’s expansive terrain, The Spike follows a single electrical response to illuminate how our extraordinary brains work.

Book Synopsis Models and Simulations of the Electric Field in Deep Brain Stimulation by : Fabiola Alonso
Download or read book Models and Simulations of the Electric Field in Deep Brain Stimulation written by Fabiola Alonso and published by Linköping University Electronic Press. This book was released on 2018-09-10 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep brain stimulation (DBS) is an established surgical therapy for movement disorders such as Parkinson’s disease (PD) and essential tremor (ET). A thin electrode is implanted in a predefined area of the brain with the use of stereotactic neurosurgery. In the last few years new DBS electrodes and systems have been developed with possibilities for using more parameters for control of the stimulation volume. In this thesis, simulations using the finite element method (FEM) have been developed and used for investigation of the electric field (EF) extension around different types of DBS lead designs (symmetric, steering) and stimulation modes (voltage, current). The electrode surrounding was represented either with a homogeneous model or a patient-specific model based on individual preoperative magnetic resonance imaging (MRI). The EF was visualized and compared for different lead designs and operating modes. In Paper I, the EF was quantitatively investigated around two lead designs (3389 and 6148) simulated to operate in voltage and current mode under acute and chronic time points following implantation.Simulations showed a major impact on the EF extension between postoperative time points which may explain the clinical decisions to change the stimulation amplitude weeks after implantation. In Paper II, the simulations were expanded to include two leads having steering function (6180, Surestim1) and patient-specific FEM simulations in the zona incerta. It was found that both the heterogeneity of the tissue and the operating mode, influence the EF distribution and that equivalent contact configurations of the leads result in similar EF. The steering mode presented larger volumes in current mode when using equivalent amplitudes. Simulations comparing DBS and intraoperative stimulation test using a microelectrode recording (MER) system (Paper III), showed that several parallel MER leads and the presence of the non-active DBS contacts influence the EF distribution and that the DBS EF volume can cover, but also extend to, other anatomical areas. Paper IV introduces a method for an objective exploitation of intraoperative stimulation test data in order to identify the optimal implant position in the thalamus of the chronic DBS lead. Patient-specific EF simulations were related to the anatomy with the help of brain atlases and the clinical effects which were quantified by accelerometers. The first results indicate that the good clinical effect in ET is due to several structures around the ventral intermediate nucleus of the thalamus.
Book Synopsis Discovering the Brain by : National Academy of Sciences
Download or read book Discovering the Brain written by National Academy of Sciences and published by National Academies Press. This book was released on 1992-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."
Book Synopsis Brain Signals by : Risto J. Ilmoniemi
Download or read book Brain Signals written by Risto J. Ilmoniemi and published by MIT Press. This book was released on 2019-05-28 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unified treatment of the generation and analysis of brain-generated electromagnetic fields. In Brain Signals, Risto Ilmoniemi and Jukka Sarvas present the basic physical and mathematical principles of magnetoencephalography (MEG) and electroencephalography (EEG), describing what kind of information is available in the neuroelectromagnetic field and how the measured MEG and EEG signals can be analyzed. Unlike most previous works on these topics, which have been collections of writings by different authors using different conventions, this book presents the material in a unified manner, providing the reader with a thorough understanding of basic principles and a firm basis for analyzing data generated by MEG and EEG. The book first provides a brief introduction to brain states and the early history of EEG and MEG, describes the generation of electromagnetic fields by neuronal activity, and discusses the electromagnetic forward problem. The authors then turn to EEG and MEG analysis, offering a review of linear and matrix algebra and basic statistics needed for analysis of the data, and presenting several analysis methods: dipole fitting; the minimum norm estimate (MNE); beamforming; the multiple signal classification algorithm (MUSIC), including RAP-MUSIC with the RAP dilemma and TRAP-MUSIC, which removes the RAP dilemma; independent component analysis (ICA); and blind source separation (BSS) with joint diagonalization.
