Using Neural Networks to Improve Cochlear Implant Speech Perception

Neural Information Processing Systems

Mter the implant, sound can be detected through the electrical stimulation of the remaining peripheral auditory nervous system. Although great progress has been achieved in this area, no useful speech recognition has been attained with either single or multiple channel cochlear implants. Coding evidence suggests that it is necessary for any implant which would effectively couple with the natural speech perception system to simulate thetemporal dispersion and other phenomena found in the natural receptors, and currently not implemented in any cochlear implants. To this end, it is presented here a computational model using artificial neural networks (ANN)to incorporate the natural phenomena in the artificial cochlear. The ANN model presents a series of advantages to the implementation of such systems.

First nanoengineered retinal implant could help the blind regain functional vision


Despite considerable advances in retinal prostheses over the last two decades, the resolution of restored vision has remained severely limited, well below the 20/200 acuity threshold of blindness. Towards drastic improvements in spatial resolution, we present a scalable architecture for retinal prostheses in which each stimulation electrode is directly activated by incident light and powered by a common voltage pulse transferred over a single wireless inductive link.

Time for an upgrade? Exploring human neural enhancement


When considering neuroprosthetics and brain-machine interfaces, cyborgs and sentient robots may come to mind – part of a not too distant dystopian future, perhaps. Popular culture leans very heavily upon speculation and the boundless imagination of readers and writers alike, often arousing apprehension and calls to forego innovation for fear of what we may unwittingly create. The question often arises of whether it is'right' to incorporate machines so closely into our bodies and minds. However, it is not necessarily a question of'right' or'wrong' but rather, and possibly more importantly, 'why'. Far removed from the imagined dystopia, neuroprosthetics are simply devices used to either replace or supplement inputs and outputs to the nervous system.

US regulators move on thought-controlled prosthetics

Patients can now guide robotic limbs using devices implanted in their brains. For the first time since accidents severed the neural connection between their brains and limbs, a small number of patients are reaching out and feeling the world with prosthetic devices wired directly to their brains. Earlier this month, scientists at the California Institute of Technology (Caltech) in Pasadena implanted a person's brain with electrode arrays that read neural activity to control a robotic arm and stimulate the brain to deliver a sensation of what the arm touched. And since 2011, a team at the University of Pittsburgh in Pennsylvania has been working with a small number of people who control prostheses through neural implants. "It's moving quick at the moment," says Christian Klaes, a neuroscientist on the Caltech effort.

Neural implants and the race to merge the human brain with Artificial Intelligence


There is a new race in Silicon Valley involving Artificial Intelligence and no it's not HealthTech, FinTech, Voice Commerce or involve Google, Facebook or Microsoft... this race involves the brain and more specifically brain-computer interfaces. This race also involves technology royalty, the US government, billion dollar defence companies, a big connection to PayPal and years of medical research to better understand the human brain and implant devices that could make a consumer brain-computer interface a reality. The race is called "Neural implants, merging the human brain with AI" So what exactly are neural implants? Brain implants, often referred to as neural implants, are technological devices that connect directly to a biological subject's brain – usually placed on the surface of the brain, or attached to the brain's cortex. A common purpose of modern brain implants and the focus of much current research is establishing a biomedical prosthesis circumventing areas in the brain that have become dysfunctional after a stroke or other head injuries.[1]
