Prof. at Sutex Bank College of Computer Applications & Science, Amroli, Surat, Gujarat - 395009 ABSTRACT Brain Gate was developed by the bio-tech company Cyber kinetics in 2003 in conjunction with the Depart- ment of Neuroscience at Brown University. The device was designed to help those who have lost control of their limbs, or other bodily functions. The computer chip, which is implanted into the brain, monitors brain activity in the patient and con- verts the intention of the user into computer commands. Currently the chip uses 100 hair-thin electrodes that 'hear' neurons firing in specific areas of the brain, for example, the area that controls arm movement. The activities are translated into electrically charged signals and are then sent and decoded using a program, thus moving the arm. According to the Cyber kinetics' website, two patients have been implanted with the Brain Gate system.

  • Neural Lace" Company
    5 Neuroscience Experts Weigh in on Elon Musk's Mysterious "Neural Lace" Company By Eliza Strickland (/author/strickland-eliza) Posted 12 Apr 2017 | 21:15 GMT Elon Musk has a reputation as the world’s greatest doer. He can propose crazy ambitious technological projects—like reusable rockets for Mars exploration and hyperloop tunnels for transcontinental rapid transit—and people just assume he’ll pull it off. So his latest venture, a new company called Neuralink that will reportedly build brain implants both for medical use and to give healthy people superpowers, has gotten the public excited about a coming era of consumer­friendly neurotech. Even neuroscientists who work in the field, who know full well how difficult it is to build working brain gear that passes muster with medical regulators, feel a sense of potential. “Elon Musk is a person who’s going to take risks and inject a lot of money, so it will be exciting to see what he gets up to,” says Thomas Oxley, a neural engineer who has been developing a medical brain implant since 2010 (he hopes to start its first clinical trial in 2018). Neuralink is still mysterious. An article in The Wall Street Journal (https://www.wsj.com/articles/elon­musk­launches­ neuralink­to­connect­brains­with­computers­1490642652) announced the company’s formation and first hires, while also spouting vague verbiage about “cranial computers” that would Image: iStockphoto serve as “a layer of artificial intelligence inside the brain.” So IEEE Spectrum asked the experts about what’s feasible in this field, and what Musk might be planning.

  • Superhuman Enhancements Via Implants: Beyond the Human Mind
    philosophies Article Superhuman Enhancements via Implants: Beyond the Human Mind Kevin Warwick Office of the Vice Chancellor, Coventry University, Priory Street, Coventry CV1 5FB, UK; [email protected] Received: 16 June 2020; Accepted: 7 August 2020; Published: 10 August 2020 Abstract: In this article, a practical look is taken at some of the possible enhancements for humans through the use of implants, particularly into the brain or nervous system. Some cognitive enhancements may not turn out to be practically useful, whereas others may turn out to be mere steps on the way to the construction of superhumans. The emphasis here is the focus on enhancements that take such recipients beyond the human norm rather than any implantations employed merely for therapy. This is divided into what we know has already been tried and tested and what remains at this time as more speculative. Five examples from the author’s own experimentation are described. Each case is looked at in detail, from the inside, to give a unique personal experience. The premise is that humans are essentially their brains and that bodies serve as interfaces between brains and the environment. The possibility of building an Interplanetary Creature, having an intelligence and possibly a consciousness of its own, is also considered. Keywords: human–machine interaction; implants; upgrading humans; superhumans; brain–computer interface 1. Introduction The future life of superhumans with fantastic abilities has been extensively investigated in philosophy, literature and film. Despite this, the concept of human enhancement can often be merely directed towards the individual, particularly someone who is deemed to have a disability, the idea being that the enhancement brings that individual back to some sort of human norm.

    Deep learning approaches for neural decoding: from CNNs to LSTMs and spikes to fMRI Jesse A. Livezey1,2,* and Joshua I. Glaser3,4,5,* [email protected], [email protected] *equal contribution 1Biological Systems and Engineering Division, Lawrence Berkeley National Laboratory, Berkeley, California, United States 2Redwood Center for Theoretical Neuroscience, University of California, Berkeley, Berkeley, California, United States 3Department of Statistics, Columbia University, New York, United States 4Zuckerman Mind Brain Behavior Institute, Columbia University, New York, United States 5Center for Theoretical Neuroscience, Columbia University, New York, United States May 21, 2020 Abstract Decoding behavior, perception, or cognitive state directly from neural signals has applications in brain-computer interface research as well as implications for systems neuroscience. In the last decade, deep learning has become the state-of-the-art method in many machine learning tasks ranging from speech recognition to image segmentation. The success of deep networks in other domains has led to a new wave of applications in neuroscience. In this article, we review deep learning approaches to neural decoding. We describe the architectures used for extracting useful features from neural recording modalities ranging from spikes to EEG. Furthermore, we explore how deep learning has been leveraged to predict common outputs including movement, speech, and vision, with a focus on how pretrained deep networks can be incorporated as priors for complex decoding targets like acoustic speech or images. Deep learning has been shown to be a useful tool for improving the accuracy and flexibility of neural decoding across a wide range of tasks, and we point out areas for future scientific development.

Maybe Not--But You Can Have Fun Trying In this chapter from his new e-book, journalist Carl Zimmer tries to reconcile the visions of techno-immortalists with the exigencies imposed by real-world biology By Carl Zimmer | Wednesday, December 22, 2010 | 14 comments Editor's Note: Carl Zimmer, author of this month's article, "100 Trillion Connections," has just brought out a much-acclaimed e-book, Brain Cuttings: 15 Journeys Through the Mind (Scott & Nix), that compiles a series of his writings on neuroscience. In this chapter, adapted from an article that was first published in Playboy, Zimmer takes the reader on a tour of the 2009 Singularity Summit in New York City. His ability to contrast the fantastical predictions of speakers at the conference with the sometimes more skeptical assessments from other scientists makes his account a fascinating read. Let's say you transfer your mind into a computer—not all at once but gradually, having electrodes inserted into your brain and then wirelessly outsourcing your faculties. Someone reroutes your vision through cameras. Someone stores your memories on a net of microprocessors. Step by step your metamorphosis continues until at last the transfer is complete. As engineers get to work boosting the performance of your electronic mind so you can now think as a god, a nurse heaves your fleshy brain into a bag of medical waste. As you —for now let's just call it "you"—start a new chapter of existence exclusively within a machine, an existence that will last as long as there are server farms and hard-disk space and the solar power to run them, are "you" still actually you? This question was being considered carefully and thoroughly by a 43-year-old man standing on a giant stage backed by high black curtains.

  • A Multi-Channel, Impedance-Matching, Wireless, Passive Recorder for Medical Applications (2019 Version)
    A Multi-Channel, Impedance-Matching, Wireless, Passive Recorder for Medical Applications (2019 Version) Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Wei-Chuan Chen, B.Eng. Graduate Program in Electrical and Computer Engineering The Ohio State University 2019 Dissertation Committee: Asimina Kiourti, Co-Advisor John L. Volakis, Co-Advisor Liang Guo Daniel Rivers © Copyright by Wei-Chuan Chen 2019 Abstract This dissertation presents a new technology for batteryless and wireless neu- rorecording system which can be applied clinically. Two clinical issues of this type of neural implant are the 1) multichannel operation and 2) high impedance and DC voltage offset from the brain electrode impedance. To resolve these two problems, one wireless multichannel system and one brain electrode interface impedance-matching system are proposed respectively. To achieve multichannel operation, one photo- activated multiplexer is employed in the implant circuit. The interrogator additionally sends an infrared control signal for channel selection. Experimental results show that the proposed neuropotential recorder exhibits 20 µVpp sensitivity at all eight channels. The system is also in compliance with the strictest Federal Communications Com- mission standards for patient safety. Notably, the proposed approach is scalable to a much higher number of channels. On the other hand, to mitigate the high impedance and DC voltage offset of the brain-electrode interface, one self-biasing PNP Bipolar Junction Transistor (BJT) is adopted in the brain circuits. This self-biasing PNP BJT increases the overall system's impedance and maintains the system sensitivity while the high impedance is present.
