Researchers provide insight into how the brain multitasks while walking:
"This research shows us that the brain is flexible and can take on additional burdens," said David Richardson, an MD/PhD student in his fifth year in the Pathology & Cell Biology of Disease Program, and first author of the study recently published in the journal NeuroImage. "Our findings showed that the walking patterns of the participants improved when they performed a cognitive task at the same time, suggesting they were actually more stable while walking and performing the task than when they were solely focused on walking."
During these experiments, researchers used a Mobile Brain/Body Imaging system, or MoBI, located in the Del Monte Institute's Frederick J. and Marion A. Schindler Cognitive Neurophysiology Lab. The platform combines virtual reality, brain monitoring, and motion capture technology. While participants walk on a treadmill or manipulate objects on a table, 16 high speed cameras record the position markers with millimeter precision, while simultaneously measuring their brain activity.
The MoBI was used to record the brain activity of participants as they walked on a treadmill and were cued to switch tasks. Their brain activity was also recorded as they performed these same tasks while sitting. Brain changes were measured between the cued tasks and showed that during the more difficult the tasks the neurophysiological difference was greater between walking and sitting -- highlighting the flexibility of a healthy brain and how it prepares for and executes tasks based on difficulty level.
