However, the influence of aging on motor-related neural mechanisms in the context of driving has rarely been studied. The present study aimed to identify age-related changes in cognitive control and attention allocation during a simulated steering task, using electroencephalography. Midfrontal theta, a marker for cognitive control, and posterior alpha power, a marker for attention allocation, were measured in a total of 26 young, 25 middle-aged, and 28 older adults. By adapting driving speed, the difficulty level of this steering task was individualized for each participant. Results show age-related changes in midfrontal theta power, but not in posterior alpha power, despite similar steering accuracy across age groups. Specifically, only younger and, to a lesser extent, middle-aged adults exhibited increased theta power while driving through more demanding curved segments relative to straight segments. In contrast, theta power upregulation was absent in older adults, suggesting a saturation of cognitive resources while driving, possibly due to a limitation in resource capacity, or less automatic motor-related neural processing. | Keywords: | Aging;Electroencephalography;Frequency band analysis;Driving performance;Driving simulation;Motor control | Document URI: | http://hdl.handle.net/1942/39065 | ISSN: | 0197-4580 | e-ISSN: | 1558-1497 | DOI: | 10.1016/j.neurobiolaging.2022.11.014 | ISI #: | 000924918900001 | Category: | A1 | Type: | Journal Contribution |
