NAUTILUS MULTI PURPOSE

g.Nautilus Multi-Purpose is specifically designed for researchers who need to measure more than brain activity alone. In addition to high-quality EEG acquisition, the system simultaneously records physiological signals such as ECG, EMG, EOG, GSR, respiration, SpO₂, pulse, and temperature, enabling synchronized brain and body monitoring from a single wearable platform. This makes it ideal for psychophysiology, human factors, sports science, cognitive neuroscience, and multimodal human performance research.

Many neuroscience questions cannot be answered by EEG alone. Simultaneously recording cardiovascular, muscular, respiratory, and autonomic physiology enables researchers to distinguish between neural, physical, and emotional responses while investigating stress, fatigue, cognitive workload, emotion, decision making, attention, and human performance. Synchronized multimodal recordings provide a much more comprehensive understanding of human behavior than isolated EEG measurements.

The four detachable physiological channels can be configured to record a wide range of biosignals, including ECG, EMG, EOG, GSR, respiration, SpO₂, pulse, temperature, and additional analog physiological sensors. These signals are acquired synchronously with EEG, enabling precise temporal alignment between brain activity and physiological responses.

Yes. g.Nautilus Multi-Purpose integrates seamlessly with g.SENSOR fNIRS, enabling synchronized EEG-fNIRS recordings for multimodal neuroimaging. Researchers can simultaneously investigate neuronal activity and cerebral hemodynamics to study neurovascular coupling, cognitive processing, motor control, rehabilitation, and Brain-Computer Interface applications.

Simultaneous acquisition ensures that EEG and physiological signals share the same time base, allowing researchers to accurately relate neural activity to cardiovascular, muscular, respiratory, and autonomic responses. This synchronization is essential for multimodal signal analysis, biosensor fusion, machine learning, and the development of predictive models of human performance and cognitive state.

g.Nautilus Multi-Purpose is designed for research that requires synchronized measurements of brain activity together with physiological responses. By simultaneously recording EEG, ECG, EMG, EOG, GSR, respiration, SpO₂, pulse, temperature, and additional biosignals, researchers can investigate how the brain and body interact during cognitive, emotional, and physical tasks.

Yes. Unlike many biosignal systems with fixed channel allocations, g.Nautilus Multi-Purpose can be configured to match your research requirements. Within the available 8-, 16-, 32-, or 64-channel hardware configurations, the number of dedicated Multi-Purpose channels can be freely allocated, for example, increasing from the standard 4 Multi-Purpose channels to 8 or more, without additional hardware costs. This allows researchers to optimize the balance between EEG and physiological recordings for their specific experimental design.
