Progress and Challenges in Brain Implants

In a paper recently published in the leading journal The Lancet Digital Health, a scientific team led by Stanisa Raspopovic from MedUni Vienna looks at the progress and challenges in the research and development of brain implants. New achievements in the field of this technology are seen as a source of hope for many patients with neurological disorders and have been making headlines recently. As neural implants have an effect not only on a physical but also on a psychological level, researchers are calling for particular ethical and scientific care when conducting clinical trials.

The research and development of neuroprostheses has entered a phase in which experiments on animal models are being followed by tests on humans.

Only recently, reports of a paraplegic patient in the USA who was implanted with a brain chip as part of a clinical trial caused a stir.

With the help of the implant, the man can control his wheelchair, operate the keyboard on his computer and use the cursor in such a way that he can even play chess.

About a month after the implantation, however, the patient realized that the precision of the cursor control was decreasing and the time between his thoughts and the computer actions was delayed.

"The problem could be partially, but not completely, resolved -- and illustrates just one of the potential challenges for research into this technology," explains study author Stanisa Raspopovic from MedUni Vienna's Center for Medical Physics and Biomedical Engineering, who published the paper together with Marcello Ienca (Technical University of Munich) and Giacomo Valle (ETH Zurich). "The questions of who will take care of the technical maintenance after the end of the study and whether the device will still be available to the patient at all after the study has been cancelled or completed are among the many aspects that need to be clarified in advance in neuroprosthesis research and development, which is predominantly industry-led."
