Abstract EN
Electrical brain activity modulation in terms of changes in its intensity and spatial distribution is a function of age and task demand.
However, the dynamics of brain modulation is unknown when it depends on external factors such as training.
The aim of this research is to verify the effect of deductive reasoning training on the modulation in the brain activity of healthy younger and older adults (N=47 (mean age of 21 ± 3.39) and N=38 (mean age of 68.92 ± 5.72)).
The analysis reveals the benefits of training, showing that it lowers cerebral activation while increasing the number of correct responses in the trained reasoning task (p<0.001).
The brain source generators were identified by time-averaging low-resolution brain electromagnetic tomography (sLORETA) current density images.
In both groups, a bilateral overactivation associated with the task and not with age was identified.
However, while the profile of bilateral activation in younger adults was symmetrical in anterior areas, in the older ones, the profile was located asymmetrically in anterior and posterior areas.
Consequently, bilaterality may be a marker of how the brain adapts to maintain cognitive function in demanding tasks in both age groups.
However, the differential bilateral locations across age groups indicate that the tendency to brain modulation is determined by age.
