Eye-movement related brain potentials during assisted navigation in real-world

Conducting neuroscience research in the real world remains challenging because of movement- and environment-related artifacts as well as missing control over stimulus presentation. The present study demonstrated that it is possible to investigate the neuronal correlates underlying visuo-spatial information processing during real-world navigation. Using mobile EEG allowed for extraction of saccade- and blink-related potentials as well as gait-related EEG activity. In combination with source-based cleaning of non-brain activity and unfolding of overlapping event-related activity, brain activity of naturally behaving humans was revealed even in a complex and dynamic city environment.
