Investigating theta tACS effects on working memory performance in healthy aging and non-amnestic MCI, suggesting optimal stimulation varies by cognitive load.
Key Points
Working memory performance improved with theta tACS in healthy aging subjects, indicating effective stimulation strategies.
Significant changes in accuracy and reaction times were noted in different cognitive loads, revealing tailored approaches are beneficial.
Single-blinded, repeated-measures design was applied with stimulation durations of 20 minutes to assess cognitive performance enhancements.
Findings imply that optimal tACS conditions may differ for MCI subjects due to variability in cognitive functions across populations.
