Soterix Medical offers integrated solutions for the simultaneous acquisition of functional Near-Infrared Spectroscopy (fNIRS) and Electroencephalography (EEG) data. This multimodal approach combines the high temporal resolution of EEG with the hemodynamic insights of fNIRS to provide a comprehensive view of brain activity. The system is specifically engineered to allow for the co-location of sensors within a single headcap while maintaining high signal integrity and minimizing electromagnetic interference between the two technologies. Supports up to 54 fNIRS channels and 64 EEG channels for high-density spatial coverage., Utilizes a specialized integrated headcap that allows for the co-location of optodes and electrodes in shared or independent holders., Validated hardware design ensures that fNIRS light-source driving currents do not introduce measurable crosstalk or artifacts into EEG recordings., Compatible with both ring and pin EEG electrodes, maintaining clear physiological signals like alpha rhythms even in hybrid configurations., Features flexible fNIRS sampling rates and shielded cabling to further protect against electromagnetic interference., Enables the simultaneous measurement of cerebral oxygenation, blood volume changes, and neuronal electrical potentials from any cortical region.
