🧠 Weekly Signal

Neurotechnology News | Aug 30 – Sep 5 2025

Let's cut through the noise this week!

This week, we saw neural implants expand into Canada and non‑invasive brain‑computer interfaces accelerate thanks to AI. Momentum continued in Alzheimer’s therapeutics and consumer neurotech research. Meanwhile, U.S. states enacted privacy laws covering neural data. Bottom line: neurotech innovation is pushing forward while regulators take notice.

🧠 SCIENCE & CLINICAL TRIALS

🟢 Neuralink’s first implants in Canada

Surgeons at Toronto Western Hospital implanted Neuralink’s wireless brain‑computer interface in two men with cervical spinal cord injuries on Aug 27 and Sept 3, the first such surgeries outside the U.S. Both patients controlled a computer cursor within minutes, and the year‑long CAN‑PRIME trial will monitor safety and function.

💡 Big Picture: Expanding trials internationally is a step toward commercial BCIs for restoring independence in paralysis.

🟢 Natural conversation maps language in epilepsy surgery

Researchers validated the Behavior‑iEEG‑Spectral‑Power‑Correlation (BESPoC) technique using intracranial EEG in 134 children. Brief natural conversations localized language areas with high specificity and sensitivity, matching electrical stimulation and high‑gamma mapping while accommodating very young or developmentally delayed patients.

💡 Big Picture: Shorter, more child‑friendly mapping could reduce surgery time and broaden epilepsy‑surgery eligibility.

🟢 AI co‑pilot boosts non‑invasive BCI performance

UCLA scientists paired a wearable EEG BCI with an AI vision system that interprets user intent and corrects errors. A participant with partial paralysis achieved a 3.9‑fold higher target‑hit rate and could complete a robotic pick‑and‑place task only with the AI. Shared autonomy substantially improved speed and accuracy for both healthy and paralyzed users.
💡 Big Picture: Combining AI with non‑invasive BCIs may deliver safer, more practical assistive technologies than implants.

💼 INDUSTRY & STARTUPS

🟢 Leqembi IQLIK offers at‑home Alzheimer’s maintenance dosing

Published: August 29, 2025
Read more ➡️ Psychiatric Times / Biogen press release

Eisai and Biogen received FDA approval for Leqembi IQLIK, a once‑weekly autoinjector delivering 360 mg of lecanemab in 15 seconds. It serves as maintenance therapy after 18 months of infusions and showed similar amyloid reduction with fewer systemic reactions in open‑label data. U.S. launch is planned for October 6.

💡 Big Picture: A convenient, at‑home option may improve adherence and broaden access to disease‑modifying Alzheimer’s therapy.

🟢 Remote brainwave study scales consumer EEG research

Published: September 5, 2025
Read more ➡️ Newsfile press release

Neuphoria and the Monroe Institute announced an IRB‑approved longitudinal study involving 333 volunteers using at‑home EEG headsets and consciousness‑training protocols. The project seeks to correlate subjective states like flow and transcendence with specific brain patterns and will build a scalable atlas of inner experiences.

💡 Big Picture: Validating remote neurofeedback could expand consumer neurotech and accelerate mental‑state research outside labs.

🏛️ POLICY & ETHICS

🟢 U.S. privacy laws now protect neural data

Published: September 2, 2025

Comprehensive privacy laws took effect in several states, granting consumers rights to opt out of data collection and requiring businesses to obtain consent before sharing personal data. Colorado, California and Montana included provisions that specifically safeguard neural data from consumer neurotech devices like earbuds and sleep headbands.

💡 Big Picture: Legislators are beginning to treat neural signals as sensitive biometric data, prompting companies to strengthen data‑protection practices.
