VRSPi: towards a neuroadaptive VR exposure therapy system for spider phobia

Integrating Electroencephalography (EEG) with Functional Magnetic Resonance Imaging (fMRI) offers researchers the unique ability to capture both the high temporal resolution of electrical activity and the superior spatial resolution of blood-flow dynamics. Brain Products provides the most comprehensive ecosystem for these demanding simultaneous recordings. Core Hardware for EEG/fMRI: BrainAmp MR / MR plus: The industry-standard amplifiers for MRI environments. These systems are non-magnetic and can be placed directly inside the scanner bore, minimizing cable length and reducing movement artifacts and induction loops., BrainCap MR: Specialized electrode caps featuring current-limiting resistors for maximum participant safety and high-quality signal acquisition during RF pulses and gradient switching., SyncBox: An essential interface that synchronizes the EEG system’s internal clock with the MRI scanner’s gradient clock, virtually eliminating jitter and facilitating the removal of gradient artifacts., Sophisticated Signal Processing: Recording EEG during MRI acquisition introduces significant artifacts, such as the Gradient Artifact (caused by magnetic field switching) and the Ballistocardiogram (BCG) artifact (caused by cardiac-related pulse movements). Brain Products' BrainVision Analyzer 2 software provides specialized transformation templates to remove these interferences, revealing the underlying neural signals with clinical-grade clarity., Safety First: All Brain Products MR-labeled hardware is rigorously tested for safety, ensuring that researchers can focus on their scientific goals while maintaining the highest standards for volunteer and patient care.
