This book was released on 2019-10-09 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vision researchers throughout the world have been working, since 1950, towards the ambitious goal of restoring a functional level of vision to the blind via electrical stimulation of the visual pathways. Groups based in Australia, USA, Germany, France and Japan report progress in the translation of retinal visual prosthetics from the experimental to clinical domains, with two retinal visual prostheses having recently received regulatory approval for clinical use. Regulatory approval for cortical visual prostheses is yet to be obtained; however, several groups report plans to conduct clinical trials in the near future, building upon the seminal clinical studies. An attempt has been made in this informative Booklet to discuss the general principles of visual prostheses employing electrical stimulation of the visual pathways, focusing on the retina and visual cortex as the two most extensively studied stimulation sites. Further to state that the surgical and functional outcomes reported to date for retinal and cortical prostheses, concluding with a brief discussion of novel developments in this field and an outlook for the future, has also been described precisely in this review for the enthusiastic Medicos. …..Dr.H.K.Saboowala.

Download or read book Clinical Ocular Prosthetics written by Keith R. Pine and published by Springer. This book was released on 2015-07-10 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first textbook to offer a comprehensive account of ocular prosthetics and the evidence used to underpin and support this field of healthcare. It does so by bringing together information from ophthalmology, prosthetic eye and contact lens literature, and from experts actively engaged in these fields. The book describes the psychological, anatomical and physiological aspects of eye loss as well as surgical procedures for removing the eye, patient evaluation, constructing prosthetic eyes (including prosthetic and surgical techniques for dealing with socket complications), the socket’s response to prosthetic eyes, prosthetic eye maintenance and the history of prosthetic eyes. Though primarily intended for prosthetists, ophthalmologists, ophthalmic nurses, optometrists and students in the fields of ocular medicine, maxillofacial medicine and anaplastology, the book also offers a useful resource for other health workers and family members who care for prosthetic eye patients, and for those patients seeking a deeper understanding of the issues affecting them than they can find elsewhere.
Download or read book Encyclopedia of Computational Neuroscience written by Dieter Jaeger and published by Springer. This book was released on 2015-02-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The annual Computational Neuroscience Meeting (CNS) began in 1990 as a small workshop called Analysis and Modeling of Neural Systems. The goal of the workshop was to explore the boundary between neuroscience and computation. Riding on the success of several seminal papers, physicists had made "Neural Networks" fashionable, and soon the quantitative methods used in these abstract model networks started permeating the methods and ideas of experimental neuroscientists. Although experimental neurophysiological approaches provided many advances, it became increasingly evident that mathematical and computational techniques would be required to achieve a comprehensive and quantitative understanding of neural system function. “Computational Neuroscience” emerged to complement experimental neurophysiology. The Encyclopedia of Computational Neuroscience, published in conjunction with the Organization for Computational Neuroscience, will be an extensive reference work consultable by both researchers and graduate level students. It will be a dynamic, living reference, updatable and containing linkouts and multimedia content whenever relevant.

Download or read book Blindsight written by Peter Watts and published by Macmillan. This book was released on 2006-10-03 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hugo and Shirley Jackson award-winning Peter Watts stands on the cutting edge of hard SF with his acclaimed novel, Blindsight Two months since the stars fell... Two months of silence, while a world held its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.
