However, only one study has evaluated rsfc as a function of driving skill. A diverse set of functional brain networks, including attention, motor control, decision making, and the sensory networks have been shown to be activated. The literature linking human brain function to driving-based movement primarily relies on simulation studies 6, 7, 8, 9. We also collected resting state (rsfc) functional MRI (fMRI) on these individuals at a single time point, so that we could begin to evaluate the relationships between brain function and movement patterns in the aging adult. Here we collected naturalistic driving data over a multi-year period in a cohort of cognitively normal older adults, giving us a very large volume of observational movement behavior data. Struggles with navigation in older adults are well documented 4, 5, and changes in movement as demonstrated by differences in how individuals move around an assisted living facility have also been found 2. As individuals age, functional movement changes can be observed 2, 3 these changes can be attributed to structural and functional changes in the brain 3. Movement ecology is a broad paradigm seeking to analyze how, why, and where organisms move 1.
