Let's cut through the noise this week!

👁️ Smartphone AI Tool for Nystagmus Diagnosis

Published: June 5, 2025

Source: Original Article

Researchers have developed a deep learning-powered smartphone system capable of diagnosing nystagmus—a neurological eye movement disorder—using standard video recordings and a cloud-based processing pipeline.

🔬 Key Details:

• The system uses video of a patient’s eyes captured via smartphone.

• A deep learning algorithm analyzes fast-phase eye movements to distinguish normal from pathological patterns.

• Tested against lab-grade videonystagmography (VNG), the system demonstrated comparable accuracy, especially in identifying horizontal jerk nystagmus.

• It leverages temporal and spatial features extracted from video frames to track eye velocity, direction, and frequency.

🔹 Why it matters:

This AI tool drastically lowers the barrier to diagnosing vestibular and neurological disorders—especially in emergency rooms, remote clinics, and underserved communities without access to expensive VNG equipment. It's a leap forward in portable, real-time neurodiagnostics with telemedicine potential.

🏥 Endovascular Oculomotor BCI in ALS Patient

Published: June 9, 2025

Researchers successfully demonstrated a minimally invasive brain-computer interface (BCI) that decodes saccadic eye movements using a Stentrode™ endovascular neural implant in a late-stage ALS patient. Unlike traditional BCIs that require open-brain surgery, the Stentrode was inserted via the jugular vein and positioned near brain regions responsible for planning eye movements.

🔬 Key Findings:

• The participant, completely paralyzed except for eye movement, performed gaze-based tasks while neural signals were recorded.

• Using machine learning, the system could distinguish between eye movement (saccade) and fixation with AUC scores >0.85.

• Direction classification (e.g. left vs. up) showed promising results, achieving up to 76% accuracy in some conditions.

• Crucially, pre-saccade signals were decodable, indicating the interface taps into cognitive planning, not just muscle movement.

🔹 Why it matters:
This is the first-ever demonstration of decoding oculomotor intent in a human using an endovascular BCI—bridging clinical safety, accuracy, and accessibility. It lays the foundation for future eye-movement-driven communication tools for individuals with severe paralysis or even complete locked-in syndrome, without needing open brain surgery.

🧠 Cognixion and Blackrock Expand Non-Invasive BCI Research with Axon‑R

Neurotech companies Cognixion and Blackrock Neurotech have partnered to expand access to Axon‑R, a non-invasive, multimodal BCI and augmented reality (AR) headset, for academic and clinical researchers. Axon‑R integrates brain signal acquisition, neurofeedback, and AR overlays into a single, wearable platform.

🔬 Key Features:

• Combines EEG, eye-tracking, and biosensors with AR interaction capabilities.

• Supports research into cognition, emotion, motor intent, and adaptive neurofeedback.

• Enables researchers to develop and test hands-free interfaces for users with communication or mobility impairments.

🧪 Who Can Use It:

• Distributed to academic institutions, hospitals, and clinics globally.

• Targeting use in ALS, autism, cerebral palsy, and rehabilitation populations.

🔹 Why it matters:
This collaboration unlocks new potential for low-barrier BCI research by offering a sophisticated, non-surgical platform with real-time neuroadaptive feedback. It empowers more labs to explore neural interaction in naturalistic settings, bridging the gap between clinical neurotechnology and consumer-grade assistive tools.
