*Further Information*

*This study investigates alterations in problem-solving and problem-solving abilities associated with aging, utilizing EEG-Brain Oscillations. The study included 30 young and 30 middle-aged subjects. During the EEG recording, four questions were used for problem-solving. The analysis focused on delta and theta oscillatory patterns. In addition, correlation analysis examined relationships between EEG data and the correct answers' scores. There was a significant result in the delta response for 0-500 ms; the young group had a higher delta response over the frontal area for arithmetic and insight questions; over the parietal area for general knowledge questions, and over the temporoparietal area for basic operation questions. The middle-aged group had a higher delta response over the occipital area for arithmetic, general knowledge, and insight questions, over the central area for basic operation questions. Theta responses showed no differences between groups or question types, remaining consistently high in the occipital area. Significant correlations existed between correct answer scores, especially temporal area. The findings underscore the diverse oscillatory profiles engendered during cognitive tasks, further indicating age-related modifications in these dynamics.
