The Zurich Center for Neuroeconomics at the University of Zurich, a leading researcher in neuroeconomics, decision making, and self-control, recently expanded their research capabilities through the acquisition of ten synchronized BIOPAC MP200 systems from NEUROSPEC. This advanced multi-subject biosignal acquisition setup enables simultaneous physiological monitoring of multiple participants during complex social decision-making experiments.
The UZH Neuroeconomics lab conducts cutting-edge research examining the physiological correlates of economic decision-making processes, particularly focusing on social interactions and strategic choice behaviors. Their experimental protocols require simultaneous ECG (heart rate variability) and respiration monitoring from multiple participants as they engage in interactive economic games and decision-making tasks.
The research paradigm involves participants making strategic decisions while their autonomic nervous system responses are continuously monitored. ECG-derived heart rate variability (HRV) parameters provide insights into cognitive load, emotional regulation, and stress responses during high-stakes decision scenarios. Concurrent respiration monitoring reveals additional autonomic indicators of decision-making processes and social interaction dynamics.
The synchronized data acquisition is critical for analyzing inter-subject physiological synchrony during collaborative or competitive decision-making tasks, enabling researchers to identify physiological markers of social coordination and strategic thinking processes.
The BIOPAC MP200 represents the gold standard for multi-channel physiological data acquisition in research environments. Key technical specifications for the neuroeconomics application include:

NEUROSPEC designed a comprehensive synchronization solution to meet the demanding requirements of multi-subject neuroeconomics research:
STP100D Synchronization Modules: Ten STP100D stimulus/trigger interface modules provide microsecond-precise synchronization across all MP200 units. Each module features:
Master Trigger System: A centralized trigger button initiates simultaneous recording across all ten MP200 systems, ensuring temporal alignment of physiological responses to experimental events. The trigger system provides:
BioNomadix Wireless Integration: The BN-RSPEC wireless modules eliminate the technical challenges associated with multi-subject wired recordings:
NEUROSPEC recommended the MP200 platform specifically for the UZH Neuroeconomics lab's multi-subject requirements based on several critical technical and methodological factors:
Temporal Synchronization Precision: The MP200's hardware-based synchronization capabilities ensure sub-millisecond alignment across all acquisition systems, essential for analyzing physiological responses to discrete decision-making events and inter-subject synchrony patterns.
Signal Quality and Artifact Rejection: The system's high common mode rejection ratio and advanced filtering algorithms maintain signal integrity despite the electrical noise inherent in multi-subject laboratory environments with computers, displays, and other electronic equipment.
Wireless Capability with Ground Isolation: The BioNomadix integration eliminates ground loop issues that commonly plague multi-subject wired setups, while allowing participants to move naturally and interact physically during experimental tasks.
Scalable Multi-Channel Architecture: The MP200 platform's modular design enables expansion from single-subject to multi-subject configurations without compromising per-channel specifications or requiring complete system redesign.
Real-Time Processing Capabilities: Hardware-based HRV calculation and respiratory parameter extraction provide immediate feedback on data quality and physiological responses, crucial for adaptive experimental protocols.
The implementation of synchronized MP200 systems has enabled the UZH Neuroeconomics lab to conduct unprecedented multi-subject physiological studies of social decision-making processes. The system's capabilities support several methodological advances:
Inter-Subject Physiological Synchrony Analysis: Synchronized data acquisition enables correlation analysis of HRV patterns between interacting participants, revealing physiological markers of social coordination and strategic alignment.
Event-Related Autonomic Response Profiling: Precise temporal synchronization with experimental stimuli allows detailed analysis of autonomic responses to specific decision events, providing insights into the temporal dynamics of economic decision-making processes.
Group-Level Physiological Dynamics: The multi-subject setup enables investigation of group-level physiological phenomena during collaborative tasks, including synchronization of respiratory patterns and heart rate dynamics during collective decision-making.
Artifact-Free Social Interaction Studies: The wireless BioNomadix integration allows natural subject interaction without movement restrictions, enabling ecologically valid social decision-making paradigms while maintaining high-quality physiological recordings.
NEUROSPEC's technical consultation and system integration for the UZH Neuroeconomics Lab demonstrates our expertise in designing sophisticated multi-subject physiological monitoring solutions for demanding research applications. The successful deployment of synchronized MP200 systems validates our technical approach to complex biosignal acquisition challenges in social neuroscience research.
This collaboration exemplifies how advanced technical planning and specialized equipment selection can enable breakthrough research methodologies in neuroeconomics and decision neuroscience, establishing NEUROSPEC as the preferred partner for cutting-edge multi-subject physiological monitoring applications.
