چکیده :

Aging is often associated with declines in sensory processing typically linked to a reduction in the brain's efficiency in processing stimuli, reduced perception, and a general decline of overall cognitive and motor performance. However, there is a compensatory mechanism in the brain that helps mitigate these effects, by increased recruitment of additional brain regions to maintain functionality and adapt to changes. In this study, we examined age-related effects on visual processing by analyzing latency and amplitude of visual evoked potentials and inter-electrode connectivity between different brain regions. Findings revealed a decrease in P1 peak amplitude as well as an increase in connectivity between frontal and occipital regions of the elderly, suggesting a compensatory mechanism and neural adaptation to sensory decline. Insight from the current study along with extensive investigation of age-related effects on sensory processing and neural communication might be helpful in designing interventions for improving cognitive health in older adults.
