To
unveil the time-of-day effect in the aging process, we recruited both young and
senior adults to participate fMRI experiments with the numerical Stroop task
before and after nap. Beyond the dorsal attention network, we found the
thalamus activity showed facilitating effect in the senior adults but the
opposite way in the young adults. Such finding supports the
compensation-related utilization of neural circuits hypothesis across age
groups, but the time-of-day effect was relatively minor compared to the age
effect.
