Behavioral Brain Research: Alpha and beta-band neurooscillation snobs predict speech and limb movement responses in normal aging.

It is not clear !---- how normal aging affects the underlying neural mechanisms of movement in older adultsin the study, two groups of young and elderly people recorded electroencephalic activity, and they performed random speech and limb movement response time tasks based on time-predictable and unpredictable sensory stimulationmethod: Older people are significantly slower than younger people during speech generation and physical movement, especially when responding to unpredictable sensory stimuli of timethis behavior effect is accompanied by the failure of alpha (7-12 Hz) and beta (13-25 Hz) in the elderly (compared to young adults), mainly in the pre-movement stage of speech generation and physical response, we found that faster motor response times in younger adults were associated with weaker pre-motion alpha and beta-band neuroactivity, and not the timing and response patterns of stimulationhowever, the pre-motion components of alpha and beta activity are time-specific in older adults and are more intensely out of step in response to time-predictable sensory stimuliresults: the role of alpha and beta band nerve oscillations in the motion timing processing mechanism was highlighted, and their functional defects were reflected in the planning stages of speech generation and limb movement during normal agingoriginal origins: Johari, Kand RBehroozmand, Event-related destruf of alpha and beta band oscillations squirts rhymp and neural lyok motor sr s in aging normalReebrain Research, 2020393: p112763.MedSci Original Source: MedSci Original, !-- Content Presentation Ends - !-- Determine signed-off-
