CERESENSO Integrated fNIRS-EEG Multimodal Positioning Cap – Hybrid Brain Imaging Solution
The CERESENSO Integrated fNIRS-EEG Multimodal Positioning Cap is an advanced, hybrid mounting system engineered for simultaneous functional Near-Infrared Spectroscopy (fNIRS) and Electroencephalography (EEG) recording. By combining the high temporal resolution of EEG with the spatial, localized hemodynamic measurement of fNIRS, this cap enables comprehensive multimodal brain imaging in cognitive neuroscience, developmental psychology, and clinical neurorehabilitation.
Constructed from heavy-duty, high-elasticity composite fabric, the cap features specially designed optical optode brackets alongside standard EEG electrode sockets. The fNIRS holder modules are clearly laser-etched with Source (S) and Detector (D) labels (such as S15, D14, S02, D02), facilitating accurate optode placement according to standard international 10-20/10-10 channel layouts. Rubberized optode rings press optical fibers firmly against the scalp, penetrating hair cleanly while preventing ambient light interference.
Key Features & Multimodal Optimization
Designed for cognitive neuroscience researchers, brain-computer interface (BCI) innovators, neurorehabilitation units, and multi-modal brain imaging laboratories.
- Dual-Modal Co-Registration: Simultaneously records electrical neural activity (EEG microvolts) and cortical blood oxygenation changes (HbO/HbR) without channel crowding or physical crosstalk.
- Standardized Source & Detector Spacing: Optode bracket arrays enforce fixed inter-optode distances (30mm standard) to ensure consistent depth of light penetration into cerebral cortex tissue.
- Permanent Optode Channel Markings: Permanent laser-engraved markings (e.g., S15, D14, S02, D02) eliminate setup errors and streamline multi-channel optical channel mapping.
- Light-Shielding Optode Grommets: Soft white silicon optode holders block external room lighting while securing optical fibers or NIRS probes flat against scalp tissue.
- Interleaved EEG Sockets: Strategically positioned low-profile EEG sockets nest between fNIRS optical channels for full scalp coverage and uncompromised EEG signal quality.
Ergonomics, Fit & Cable Management
Engineered to reduce motion artifacts and simplify complex multi-fiber harness setups during behavioral experiments.
- Reinforced Heavy-Duty Fiber Routing: Sturdy mounting plates absorb the mechanical weight and torque of heavy fiber-optic cables, keeping probe tips perpendicular to the head.
- Adjustable Chin Anchor System: Padded chin strap maintains constant vertical elasticity, ensuring both optical probes and gel/saline EEG electrodes remain securely coupled during subject motion.
- Durable & Washable Fabric Substrate: Smooth synthetic fabric cleans easily after gel or saline removal and maintains shape retention over long research protocols.
Broad Applications in Multimodal Brain Imaging
Ideal for university neuroimaging centers, cognitive psychology labs, infant and pediatric developmental studies, and advanced closed-loop BCI systems.

Frequently Asked Questions (FAQ)
Is this cap compatible with commercial fNIRS hardware systems?
Yes. The optode holders are designed to accept optical probes and fibers from major fNIRS manufacturers (such as NIRx, Shimadzu, Artinis, Hitachi, and TechEn) as well as custom open-source optical hardware.
How does the cap prevent light leakage during fNIRS measurements?
The holders feature flexible silicon/rubber grommets that form a tight seal around the optode tip against the scalp, preventing ambient room light from penetrating the detector channel and ruining signal quality.
Can I use saline sponge electrodes instead of gel electrodes for the EEG channels?
Yes. The cap can be configured with plug-in saline sponge sockets or low-profile gel electrode sockets depending on your laboratory’s preference for rapid setup or long-term recording.
What is the benefit of simultaneous fNIRS and EEG recording?
Combining fNIRS and EEG allows researchers to correlate fast electrophysiological neural firing (milliseconds via EEG) with localized vascular hemodynamic responses (blood oxygenation via fNIRS), providing a comprehensive multi-parameter view of brain activity.
