Multimodal Neuromodulation: Integrating tPBM with HD-tES and EEG

Soterix Medical provides a groundbreaking integrated platform that combines transcranial Photobiomodulation (tPBM) with High-Definition transcranial Electrical Stimulation (HD-tES) and EEG recording. This triple-modality capability allows researchers to deliver light and electricity to the brain while simultaneously measuring the brain's electrical response. How the Integration Works. The core of this solution is the NeuroThera NT-200. Unlike traditional bulky lasers, the NT-200 utilizes compact laser modules designed specifically for multimodal research:. Cap-Mountable Modules: Emitters snap directly into standard plastic holders, the same used for HD-tES electrodes and EEG sensors., Unified Headgear: Utilizing the Soterix Medical HD-Cap, users can place laser diodes, stimulation electrodes, and recording sensors in precise anatomical locations according to the 10/10 or 10/20 international systems., Synchronized Workflow: The system is engineered to prevent interference between electrical stimulation, laser light, and sensitive EEG signals, ensuring clean data for analysis. Key Benefits of the Triple-Modality Approach:. Synergistic Effects: Researchers can study how light (boosting cellular ATP/energy) and electricity (modulating neural firing) work in tandem to produce enhanced clinical outcomes., Real-Time Feedback: EEG allows for immediate observation of how brain activity changes the moment light or current is applied., Anatomical Precision: Ensuring both energy sources hit the exact same cortical target through shared positioning hardware., Streamlined Setup: A single, lightweight cap reduces subject burden and setup time compared to multiple individual devices. Technical Capabilities:. Wavelength Precision: Delivery of 808 nm near-infrared light alongside customizable electrical waveforms., Multi-Channel Configuration : Setup up to 8 laser beams concurrently with high-definition stimulation., Interference-Free Design: Advanced shielding eliminates "noise" in EEG recordings from the laser driver or electrical stimulator.
