8 EEG Labs & Neurophysiology Companies for Clinical Trials in 2026

Electroencephalography has become a central tool for measuring brain activity in CNS clinical trials, whether the goal is quantifying seizure frequency, tracking sleep architecture, or generating an objective biomarker of a drug's effect on the brain. An EEG lab might specialize in centralized reading and biomarker discovery, the technologists and equipment needed to acquire high-quality signal at a patient's bedside or home, or the wearable hardware that makes EEG collection possible outside a hospital setting. For Sponsors and CROs evaluating an EEG lab for a clinical trial, the choice often comes down to whether a study needs full-service centralized analysis, acquisition staffing and logistics, or a validated device to pair with an existing vendor relationship.

The companies below, presented in no particular order, span that range. Between them they cover AI-driven EEG biomarker platforms, dedicated EEG and sleep core labs, turnkey acquisition and technologist services, and the wearable and point-of-care hardware used to capture EEG signal in decentralized and emergency settings.

Beacon Biosignals

Beacon Biosignals combines an FDA-cleared wearable EEG headband, Waveband, with an AI platform that generates sleep and brain biomarkers for use across the drug development lifecycle, from clinical trial design to biomarker discovery. Founded in 2019 in Boston as Checkpoint AI, the company states its technology is used in more than 40 clinical trials globally across conditions including depression, schizophrenia, Alzheimer's, and Parkinson's disease. In June 2026 Beacon completed the integration of CleveMed into the Beacon brand, unifying its technology and clinical services under one name following a series of raises that brought its total funding above $130 million.

CortiCare

CortiCare operates the first and one of the largest tele-EEG services in the US, providing nationwide remote EEG monitoring, technologist coverage, and physician-led interpretation for hospitals, neurology practices, and in-home ambulatory studies. Founded in 2012, the company states it employs more than 200 EEG technologists and has achieved half a million hours of annual continuous EEG monitoring, growing in part through its acquisition of Arium EEG and other regional EEG providers. CortiCare was acquired by 1315 Capital to support its continued growth and client solutions.

Lifelines Neuro (Synthesys Brain Health)

Lifelines Neuro provides a turnkey EEG solution for clinical trials, spanning protocol design, EEG hardware and cloud-based software, technologist-led data acquisition, and centralized data management and reporting. Founded in 2014 and based in Louisville, Kentucky, the company states its clinical trials team draws on more than 150 years of combined EEG experience. In 2023 Lifelines Neuro formed Synthesys Brain Health, a joint venture with Neurovative Diagnostics and Ambulatory Neurological Services, combining EEG hardware, software, and diagnostic services into a single Neuro-Ecosystem.

Great Lakes NeuroTechnologies

Great Lakes NeuroTechnologies develops bioinstrumentation products for physiological monitoring, including its FDA-cleared and CE-marked Kinesia motor assessment system, used by more than 20 pharmaceutical companies in Parkinson's disease clinical trials to generate validated outcome measures. Based in Cleveland, Ohio, the company also markets KinesiaU, a smartwatch-based version of its motor assessment technology recommended by the UK's NICE for remote Parkinson's monitoring in the NHS. Great Lakes NeuroTechnologies' wireless, web-connected physiological monitors support research, education, and telemedicine applications beyond movement disorders.

The Siesta Group

The Siesta Group specializes in measuring sleep, wakefulness, and brain activity for clinical trials, offering consulting, site training, centralized EEG and polysomnography scoring, and device rental services. Founded in 2002 and based in Vienna, Austria, the company developed Somnolyzer 24x7, a computer-assisted sleep scoring tool later acquired by Philips-Respironics for the clinical and diagnostic sleep lab market, while The Siesta Group retained the clinical trial and research applications. The Siesta Group has also offered preclinical EEG services, including sleep staging and spectral analysis in rodent studies, since 2009.

Clouds of Care

Clouds of Care provides EEG-based biomarker services for rare and complex CNS clinical trials, combining electrophysiology expertise with an AI platform for endpoint validation, and the company states it is the only global company specializing in this niche, with a particular track record in epilepsy and developmental and epileptic encephalopathies. Founded as Epilog, a spin-off from Ghent University, Antwerp University, and imec, the Belgium-based company rebranded as Clouds of Care to expand from epilepsy into broader CNS indications including Alzheimer's and Parkinson's disease. The company secured 5 million euros in funding in 2024 and appointed former Biogen CEO Michel Vounatsos as chairman of its board.

Neurovirtual

Neurovirtual manufactures neurology and sleep diagnostics equipment, including its BW3 system, which the company states was the first to combine full Type 1 polysomnography with epilepsy montage and full EEG, quantitative EEG, video EEG, and long-term monitoring in a single FDA-cleared device. The company traces its roots to 1969 as an EEG paper manufacturer and is now headquartered in Fort Lauderdale, Florida, with subsidiaries in Germany and other markets. Neurovirtual states it has served more than 3,000 customers globally with its EEG and polysomnography hardware and BWAnalysis software suite.

BrainScope

BrainScope develops handheld, EEG-based medical devices for assessing traumatic brain injury and concussion at the point of care, and the company states its device was the first in neurology cleared by the FDA under the AI/Machine Learning-Enabled Medical Device category. Based in Bethesda, Maryland, the company developed its technology in partnership with the US Department of Defense, and its FDA-cleared algorithms have been shown to reduce unnecessary head CT scans by roughly 30% to 50% in emergency department settings. BrainScope's biomarkers can also be applied to EEG data captured by third-party devices beyond its own proprietary hardware.
