EEG

Researchers have proposed MSARFNet, a multi-scale attention-based reconstruction fusion network that reached average classification accuracies of 84.64% and 87.96% on the BCI Competition IV 2a and 2b motor imagery datasets, outperforming several existing methods. The network extracts spatio-temporal features through parallel multi-scale convolutional branches and fuses them with an attention mechanism to sharpen transient motor-imagery responses, targeting the non-stationary EEG signals and inter-subject variability that make MI decoding unreliable. The study was published on February 27, 2026, in IEEE Journal of Biomedical and Health Informatics.

The FDA cleared Clouds of Care's PreOp v3 on February 13, 2026, finding it substantially equivalent under submission number K252565 through the special 510(k) pathway. The agency classifies it as Source Localization Software for Electroencephalograph or Magnetoencephalograph, a Class II device under regulation 882.1400, with neurology as the assigned review panel. Source localization software infers the intracranial origin of signals from scalp-recorded electric or magnetic fields, a step in neurosurgical planning such as presurgical localization of epileptic foci.

The FDA cleared the Ceribell Delirium Monitor System on December 8, 2025, finding it substantially equivalent under submission number K251936 through the traditional 510(k) pathway. The agency classifies it as a Neuropsychiatric Interpretative Electroencephalograph Assessment Aid, a Class II device under regulation 882.1440, with neurology as the assigned review panel. The category covers devices that derive neuropsychiatric assessments from EEG signals; Ceribell's earlier products in this line target seizure monitoring in emergency and intensive care settings.

The FDA cleared Hippoclinic's HippoMind, version 1.0, on December 3, 2025, finding it substantially equivalent under submission number K251881 through the traditional 510(k) pathway. The agency classifies it as Non-Normalizing Quantitative Electroencephalograph Software, a Class II device under regulation 882.1400, with neurology as the assigned review panel. Unlike normalizing tools, non-normalizing quantitative EEG software reports an individual's own EEG metrics without reference to a population database.

The FDA cleared Naox Technologies' NX01 on November 25, 2025, finding it substantially equivalent under submission number K251550 through the traditional 510(k) pathway. The agency classifies it as a Reduced-Montage Standard Electroencephalograph, a Class II device under regulation 882.1400, with neurology as the assigned review panel. Reduced-montage systems record with fewer electrodes than a conventional clinical montage, trading spatial resolution for faster setup and the possibility of wearable form factors.

The US Food and Drug Administration cleared Ceribell, Inc.'s Ceribell Infant Seizure Detection Software on November 21, 2025, finding it substantially equivalent under submission number K252070 via the Traditional 510(k) pathway. FDA lists it as Automatic Event Detection Software for Full-Montage Electroencephalograph, a Class II device under regulation number 882.1400, reviewed by the agency's neurology advisory committee. Neonatal EEG looks markedly different from adult morphology, which has long made automated interpretation difficult; the classification covers software that flags events automatically in full-montage recordings.

The FDA cleared Persyst Development's Persyst 15 EEG Review and Analysis Software on October 31, 2025, finding it substantially equivalent under submission number K252160 through the traditional 510(k) pathway. The agency classifies it as Automatic Event Detection Software for Full-Montage Electroencephalograph, a Class II device under regulation 882.1400, with neurology as the assigned review panel. The category covers software that automatically flags events within full-montage EEG recordings for clinician review.

Nihon Kohden's EEG-1260A Neurofax system, along with its amplifier unit and photic stimulator, received FDA 510(k) clearance on October 9, 2025. The device is a Class II medical device in the neurology specialty, with software for quantitative EEG analysis. The traditional 510(k) clearance indicates substantial equivalence to a legally marketed device.

The FDA cleared Forest Devices' SignalNED System (Model RE) on September 3, 2025, finding it substantially equivalent under submission number K251726 through the traditional 510(k) pathway. The agency classifies it as a Reduced-Montage Standard Electroencephalograph, a Class II device under regulation 882.1400, with neurology as the assigned review panel. Forest Devices has applied reduced-montage EEG to prehospital stroke identification, acquiring interpretable signals in settings such as ambulances.
