Cognition in action: imaging brain/body dynamics in mobile humans

Area of Science:

• Neuroscience
• Cognitive Science
• Biomedical Engineering

Background:

• Cognitive processes are deeply intertwined with physical actions and the human body.
• Existing brain imaging techniques limit the study of cognition during natural, active behaviors.
• Understanding brain-body dynamics is crucial for comprehending goal-directed actions.

Purpose of the Study:

• To introduce a novel mobile brain imaging (MoBI) method for simultaneous brain and body dynamics recording.
• To explore the coupling between physical structure, cognitive processing, and supraspinal control during behavior.
• To demonstrate the feasibility and versatility of MoBI for investigating a wide range of human behaviors.

Main Methods:

• Development of a mobile brain imaging (MoBI) system.
• Integration of advanced sensor technologies for recording diverse behavioral states.
• Simultaneous capture of neural activity and detailed body movement dynamics.

Main Results:

• MoBI enables the study of cognitive processes during active, real-world interactions.
• Evidence presented on the tight coupling between physical structure and cognitive functions.
• Demonstration of supraspinal activity's role in controlling human posture and locomotion.

Conclusions:

• The developed MoBI system is a feasible and powerful tool for neuroscience research.
• MoBI opens new avenues for investigating complex cognitive-behavioral interactions.
• This method advances the study of how the brain controls embodied actions.
