    Meta’s AI Achieves 80% Accuracy in Mind Reading Technology

    Key Takeaways

    1. Meta’s AI can reconstruct sentences from brain activity with 80% accuracy, aiding those who have lost speech.
    2. The research uses non-invasive methods (MEG and EEG) to capture brain activity without surgery.
    3. Limitations include the need for a magnetically shielded environment and the requirement for participants to remain still.
    4. The AI helps understand how the brain translates thoughts into language, revealing a ‘dynamic neural code.’
    5. Meta is investing in further research with a $2.2 million donation and partnerships with various European institutions.

    Meta’s AI research team is making strides in understanding human thoughts. In partnership with the Basque Center on Cognition, Brain, and Language, the company has created an AI model that can reconstruct sentences from brain activity with accuracy reaching 80%. This research uses a non-invasive method for recording brain activity and, as stated by the company, could lead to technology that assists those who have lost the ability to speak.

    The Technology Behind It

    Differing from current brain-computer interfaces that typically need invasive procedures, Meta employs magnetoencephalography (MEG) and electroencephalography (EEG). These methods capture brain activity without any surgery involved. The AI model was trained on recordings from 35 participants while they typed sentences. When faced with new sentences, Meta asserts that it can predict up to 80% of the typed characters using MEG data—this is at least double the effectiveness of EEG-based decoding.

    Limitations and Challenges

    However, there are certain limitations to this approach. MEG necessitates a magnetically shielded environment, and participants have to remain completely still for precise readings. Furthermore, this technology has only been evaluated on healthy individuals, leaving its performance for those with brain injuries uncertain.

    Understanding Word Formation

    In addition to decoding thoughts into text, Meta’s AI is assisting researchers in comprehending how the brain converts ideas into language. The AI model scrutinizes MEG recordings, observing brain activity in milliseconds. It uncovers how the brain changes abstract thoughts into words, syllables, and even the movements of fingers while typing.

    A significant discovery is that the brain utilizes a ‘dynamic neural code,’ which connects various stages of language creation while keeping previous information readily accessible. This might shed light on how individuals effortlessly construct sentences while communicating.

    Meta’s research reinforces the idea that AI could eventually facilitate non-invasive brain-computer interfaces for those unable to communicate verbally. Nevertheless, the technology is not yet ready for practical application. There is a need for improved decoding accuracy, and the hardware requirements of MEG limit its usability outside of laboratory environments.

    Meta is committed to fostering this research by forming partnerships. The company has pledged a donation of $2.2 million to the Rothschild Foundation Hospital to aid ongoing research. It is also collaborating with institutions such as NeuroSpin, Inria, and CNRS in Europe.

  • Use Apple Vision Pro to Control Devices with Your Thoughts

    Use Apple Vision Pro to Control Devices with Your Thoughts

    Synchron has created a non-invasive brain-computer interface that allows users to control devices such as the Apple Vision Pro. This technology has been in use for a year and has not led to any serious negative effects for patients.

    Empowering Individuals with Disabilities

    For those who may not know, a brain-computer interface (BCI) is a system that enables individuals to control external devices using signals from their brain. It serves as a valuable tool for people with disabilities, including those who are paralyzed, and is also beneficial for scientific research.

    Synchron’s brain implants, which are minimally invasive, began their clinical trials in 2022. Initially developed to control iPhones and iPads, these implants have now advanced to managing more sophisticated devices like the Apple Vision Pro.

    Safety and Effectiveness

    According to Synchron, six patients who received BCI implants did not encounter significant adverse effects related to the device during the first year. Essentially, the implanted device functioned reliably, successfully capturing signals that indicate brain movement intentions without causing any issues.

    Importantly, the COMMAND study is the first trial approved by the FDA for a permanently implanted brain-computer interface. Unlike other brain implants that necessitate risky, invasive surgery, Synchron’s device is inserted through a minimally invasive endovascular method via the jugular vein.

    A Milestone in Medical Research

    “The outcomes of the COMMAND study represent a significant milestone in medicine, affirming the safety of the Stentrode BCI, with no neurological safety incidents reported throughout the 12-month observation period,” stated Dr. Levy, co-principal investigator of the COMMAND trial and president of UB Neurosurgery (UBNS). “This minimally invasive method could make BCI technology accessible to millions of individuals suffering from paralysis and other mobility challenges.”

    Aiming for Functional Independence

    The primary aim of this implant is to assist individuals paralyzed due to conditions like stroke or severe brain injuries in regaining some level of functional independence. The patients involved in the initial trial all exhibited severe, chronic bilateral upper limb paralysis that did not respond to conventional treatments.

    In conclusion, a brain-computer interface has the ability to interpret brain signals and convert them into actions necessary for operating devices, such as those from Apple, enabling users to perform specific tasks despite physical limitations.

    Elon Musk: Neuralink to Implant Chips in 1,000+ Patients by 2026

    Elon Musk’s Neuralink, a firm focused on developing brain-computer interfaces, has set a lofty goal: implanting chips in over 1,000 patients by 2026. The announcement was made on Musk’s X (Twitter) platform on July 11th.

    Life-Changing Technology for Paralyzed Patients

    The technology has proven to be transformative for some individuals. Noland Arbaugh, the first person to receive a Neuralink implant, shared publicly how it has enhanced his life. Previously paralyzed from the neck down, Arbaugh faced challenges in interacting with technology. Post-surgery, he can now use devices and even play video games effortlessly.

    Setbacks and Stability

    Despite the promising advancements, there have been obstacles. In May, a small wire in Arbaugh’s brain shifted. Nonetheless, a Neuralink executive recently assured that the brain-computer interface chip is now “more or less very stable.”

    Future Goals and Vision

    During a live broadcast earlier on July 11th (Beijing time), Musk detailed Neuralink’s future objectives. He aims to implant the chip in thousands of patients over the next few years. Neuralink’s technology enables patients to control robotic limbs with their minds, surpassing the speed of natural brain-limb connections. Musk envisions an even bigger mission: creating a symbiotic relationship between humans and artificial intelligence to mitigate the risks AI poses to civilization.
