fNIRS + Biosignals Integration: Cortivision & Bitbrain Versatile Bio

Human behavior and cognition are not isolated to the brain; they manifest throughout the entire body. By integrating functional Near-Infrared Spectroscopy (fNIRS) with advanced neurophysiological biosensors , researchers can leverage the strengths of multiple techniques to obtain a holistic, synchronized view of neural and bodily functions. Hardware Synergy: Cortivision & Versatile Bio. The integration of Cortivision fNIRS systems with the Bitbrain Versatile Bio amplifier offers a comprehensive and fully mobile solution optimized for both laboratory and real-world field studies. Comprehensive Biosignal Collection: The Versatile Bio is a compact, multipurpose amplifier capable of monitoring up to 35 physiological variables. Compatible sensors include ExG (ECG, EMG, EOG), Galvanic Skin Response (GSR), Blood Volume Pulse (BVP), respiration (air flow), temperature, and built-in IMUs (accelerometer and gyroscope)., Total Freedom of Movement: Designed for outstanding usability, the bio-amplifier can be comfortably strapped to the participant's arm, waist, or leg, working perfectly in tandem with Cortivision's lightweight, wearable fNIRS caps., Uncompromised Signal Quality: Operating at up to 256Hz and 24 bits for over 8 hours, the system features active shielding and optimized Driven Right Leg (DRL) circuitry to improve the Signal-to-Noise Ratio (SNR) and reduce motion artifacts. Precise Synchronization via LSL:. To ensure that every heartbeat, muscle twitch, and skin conductance spike is perfectly aligned with the corresponding change in cortical oxygenation, both Cortivision and Bitbrain systems utilize the Lab Streaming Layer (LSL) protocol for robust, millisecond-accurate data synchronization. Key Research Applications:. Brain-Computer Interfaces (BCI): Develop hybrid BCIs that utilize both central nervous system (fNIRS) and peripheral nervous system (EMG) inputs for more reliable decoding., Movement & Sports Science: Monitor cognitive-motor interactions during physical activity, rehabilitation, and sports training with highly artifact-resistant hardware., VR & Multimodal Studies: Evaluate emotional arousal (GSR/BVP) and cognitive workload (fNIRS) simultaneously during immersive Virtual Reality experiences.
