The vOICe vision BCI 🧠🇪🇺

Yes, this is an AI-generated fictional video, but blind users of The vOICe for Android are generally very pleased with the various types of stand-alone Vuzix smart glasses. Vuzix glasses are not cheap but we love them and are grateful for the consistent Vuzix support over the years. Elon Musk's Neuralink Blindsight will turn out to be no match. Everything we do is scalable, relatively affordable, and future-proof artificialvision.com/neuralink

The new company Nudge nudge.com is with the help of quite a few ex-Neuralink employees developing a phased array ultrasound helmet for transcranial focused ultrasound stimulation (tUS/tFUS) of the human brain. #BCI #NeuroTech #neuroscience

Theoretically, the phased array ultrasound helmet being developed by Nudge could lead to a non-invasive visual prosthesis through transcranial focused ultrasound stimulation (tUS/tFUS) of primary visual cortex V1 at ~1 mm focus spots.

"A man w/ amyotrophic lateral sclerosis (ALS) who had lost his ability to speak has been able to communicate w/ a Blackrock Neurotech text-to-speech brain implant, researchers said in one of two new studies showing the promise of brain-computer interfaces for restoring speech in paralyzed patients."

"If you take it for granted that nobody can listen in on your innermost thoughts, I regret to inform you that your brain may not be private much longer. Luckily, the brain is lawyering up." Colorado passed legislation to prevent companies from selling your brainwaves. But is it enough to stop the likes of Meta and Apple?

Enhancing prosthetic vision by upgrade of a subretinal photovoltaic implant in situ (in rats) biorxiv.org/content/10.1101/20 "demonstrates the feasibility of safely upgrading the subretinal photovoltaic implants to improve prosthetic visual acuity"; retinal implant, #BCI #NeuroTech

bioRxiv · Enhancing Prosthetic Vision by Upgrade of a Subretinal Photovoltaic Implant in situIn patients with atrophic age-related macular degeneration, subretinal photovoltaic implant (PRIMA) provided visual acuity up to 20/440, matching its 100μm pixels size. Next-generation implants with smaller pixels should significantly improve the acuity. This study in rats evaluates removal of a subretinal implant, replacement with a newer device, and the resulting grating acuity in-vivo. Six weeks after the initial implantation with planar and 3-dimensional devices, the retina was re-detached, and the devices were successfully removed. Histology demonstrated a preserved inner nuclear layer. Re-implantation of new devices into the same location demonstrated retinal re-attachment to a new implant. New devices with 22μm pixels increased the grating acuity from the 100μm capability of PRIMA implants to 28μm, reaching the limit of natural resolution in rats. Reimplanted devices exhibited the same stimulation threshold as for the first implantation of the same implants in a control group. This study demonstrates the feasibility of safely upgrading the subretinal photovoltaic implants to improve prosthetic visual acuity. ### Competing Interest Statement Ted Kamins: Consultant (Pixium Vision) Daniel Palanker: Patent, Consultant (Pixium Vision) Other authors have no other competing interests to declare.

New informative article re: #neurotech #neuroethics #BCI #AI. Worth a read. "Developer perspectives on the ethics of AI-driven neural implants: a qualitative study."
Nature (4/3/2024)

nature.com/articles/s41598-024

NatureDeveloper perspectives on the ethics of AI-driven neural implants: a qualitative study - Scientific ReportsConvergence of neural implants with artificial intelligence (AI) presents opportunities for the development of novel neural implants and improvement of existing neurotechnologies. While such technological innovation carries great promise for the restoration of neurological functions, they also raise ethical challenges. Developers of AI-driven neural implants possess valuable knowledge on the possibilities, limitations and challenges raised by these innovations; yet their perspectives are underrepresented in academic literature. This study aims to explore perspectives of developers of neurotechnology to outline ethical implications of three AI-driven neural implants: a cochlear implant, a visual neural implant, and a motor intention decoding speech-brain-computer-interface. We conducted semi-structured focus groups with developers (n = 19) of AI-driven neural implants. Respondents shared ethically relevant considerations about AI-driven neural implants that we clustered into three themes: (1) design aspects; (2) challenges in clinical trials; (3) impact on users and society. Developers considered accuracy and reliability of AI-driven neural implants conditional for users’ safety, authenticity, and mental privacy. These needs were magnified by the convergence with AI. Yet, the need for accuracy and reliability may also conflict with potential benefits of AI in terms of efficiency and complex data interpretation. We discuss strategies to mitigate these challenges.
