Hypothesis
The study examines the relationship between resting state EEG activity and inhibitory control performance in cognitively unimpaired older adults.
Conclusion
Lower resting state alpha power is associated with better accuracy and lower alpha ERD during inhibitory control tasks in older adults.
Supporting Evidence
- Lower absolute alpha power in resting state was correlated with better accuracy on Go trials.
- Lower alpha ERD was also correlated with better performance on Go trials.
Takeaway
This study found that how the brain behaves when resting can help predict how well older adults can control their actions.
Methodology
EEG data were collected during resting state and a Go/NoGo task, with spectral analysis performed on the alpha frequency band.
Participant Demographics
Cognitively unimpaired older adults, average age 64.04 years.
