Recalibration of inhibitory control systems during walking-related dual-task interference: A Mobile Brain-Body Imaging (MOBI) Study

Pierfilippo De Sanctis, John S. Butler, Brenda R. Malcolm, John J. Foxe
2014 NeuroImage  
We applied an EEG-based Mobile Brain-Body Imaging (MOBI) system that integrates high-density event-related potential (ERP) recordings with simultaneously acquired foot-force sensor data to monitor gait  ...  We found robust differences in amplitude, latency and topography of ERP components (N2 and P3) associated with inhibitory control between the sitting and walking conditions.  ...  Acknowledgments Sincere thanks go to Jason Green for help setting up the MOBI system and for data recording.
