During normal aging resting-state brain activity changes and working memory
performance declines as compared to young adulthood. Interestingly, previous studies
reported that different electroencephalographic (EEG) measures of resting-state brain
activity may correlate with working memory performance at different ages. Here, we
recorded resting-state EEG activity and tested allocentric spatial working memory in
healthy young (20–30 years) and older (65–75 years) adults. We adapted standard EEG
methods to record brain activity in mobile participants in a non-shielded environment,
in both eyes closed and eyes open conditions. Our study revealed some age-group
differences in resting-state brain activity that were consistent with previous results
obtained in different recording conditions. We confirmed that age-group differences
in resting-state EEG activity depend on the recording conditions and the specific
parameters considered. Nevertheless, lower theta-band and alpha-band frequencies
and absolute powers, and higher beta-band and gamma-band relative powers were
overall observed in healthy older adults, as compared to healthy young adults. In
addition, using principal component and regression analyses, we found that the first
extracted EEG component, which represented mainly theta, alpha and beta powers,
correlated with spatial working memory performance in older adults, but not in
young adults. These findings are consistent with the theory that the neurobiological
bases of working memory performance may differ between young and older adults.
However, individual measures of resting-state EEG activity could not be used as reliable
biomarkers to predict individual allocentric spatial working memory performance in
young or older adults.
