Effects of second language learning on the plastic aging brain: Functional connectivity, cognitive decline, and reorganization

摘要: Learning a new language requires the use of extensive neural networks and can represent powerful tool to reorganize brain neuroplasticity. In this study, we analyze how 4 months long second learning program (16, 2 h sessions) lead functional changes in healthy elderly individuals. A large number studies point out decline brain-skills with age; here it is analyzed cognition together organization be improved later life. Twenty-six older adults (59-79 years old) were enrolled present study. complete neuropsychological examination was administered before after intervention measure global levels, short- long-term memory, attention, access executive functions. At end program, group, results showed significant improvement an increased connectivity right inferior frontal gyrus (rIFG), superior (rSFG) left parietal lobule (lSPL). These findings added current neurobiological breakthroughs reshaping short practice subjects. Therefore, foreign-language may potentially helpful cognitive for promoting aging.
