Feasibility Study of the BrainGate Neural Interface System

Interim Safety Profile From the Feasibility Study of the BrainGate Neural Interface System Brain computer interfaces (BCIs) are being developed to restore mobility, communication, and functional independence to people with paralysis. Though supported by decades of preclinical data, the safety of chronically implanted microelectrode array BCIs in humans is unknown....

Brain stimulation boosts hearing in rats with ear implants

Study identifies neurons that can improve sound perception, which could explain the variation in performance in people with cochlear devices. Stimulating neurons that are linked to alertness helps rats with cochlear implants learn to quickly recognize tunes, researchers have found. The results suggest that activity in a brain region called...

Optimal deep brain stimulation sites and networks for stimulation of the fornix in Alzheimer’s disease

Deep brain stimulation (DBS) to the fornix is an investigational treatment for patients with mild Alzheimer’s Disease. Outcomes from randomized clinical trials have shown that cognitive function improved in some patients but deteriorated in others. This could be explained by variance in electrode placement leading to differential engagement of neural...

Musk intends to implant brain computer chips in humans in 2023

Elon Musk and one of his other companies intend to begin testing computer chips in the brain next year. Neuralink will be able to insert the implant into a person's brain in 06-2023, Musk announced at his startup's annual press conference. The interface produced by Neuralink will make it possible...

implant, that turns brain waves into words

A computer screen shows the question “Would you like some water?” Underneath, three dots blink, followed by words that appear, one at a time: “No I am not thirsty.” It was brain activity that made those words materialize—the brain of a man who has not spoken for more than 15...

Maturation and circuit integration of transplanted human cortical organoids

Self-organizing neural organoids represent a promising in vitro platform with which to model human development and disease. However, organoids lack the connectivity that exists in vivo, which limits maturation and makes integration with other circuits that control behaviour impossible. Here we show that human stem cell-derived cortical organoids transplanted into the...

Artificial neuron for neuromorphic sensing and biointerfacing

The effective mimicry of neurons is key to the development of neuromorphic electronics. However, artificial neurons are not typically capable of operating in biological environments, which limits their ability to interface with biological components and to offer realistic neuronal emulation. We report an organic artificial neuron that is based on...

If a neurological remote controlled implant is no longer supported

A patient report noted that he found no further support after the withdrawal of the manufacturer of a neurostimulating implant. The device is implanted in the maxilla. He had a cluster headache that was relieved by the device. In another case, distribution of an ocular implant was discontinued because it...
