Playing puzzles can help prevent neurocognitive disorder by stimulating cognitive functions in the brain. Research by Fissler et al. (2017) with 100 participants declares that puzzles can be used to enrich cognitive abilities or PACE (Puzzles as Cognitive Enrichment). Research about the effects of playing puzzles can be observed with EEG. The main aim of this study is to find out the effects of playing puzzles on brain activity. Measurement of two brain waves, Beta and Gamma, was done using MUSE EEG at left (TP9) and right (TP10) electrodes, which measures the activity of the temporoparietal lobe. The recording was done while the participant played the puzzle to obtain ABP (Absolute Brain Power) value. A total of 6 participants (3 male and 3 female) participate in this study. Brain activity recording was done in 2 stages: (1) while not playing puzzle (baseline) for 1 minute, then (2) continue while playing puzzle with maximal duration of 10 minutes. Analysis of the EEG recordings shows Gamma activity for 5 participants at TP9 and all 6 participants at TP10 and Beta activity for all 6 participants at TP9 and TP10 significantly shows higher ABP means while playing puzzle compared to baseline or not playing puzzle (p<0,05). Analysis between two brain hemisphere, Beta activity is not significantly different (p>0,05) for female participant at all condition and higher at right hemisphere for male participant at playing puzzle condition (p<0,05), whereas Gamma activity at left hemisphere is higher than right hemisphere (p<0,05) for female and male at all condition. Female participants have higher Beta (except for playing puzzle condition at TP10) and Gamma (at all condition and channel) activity than male (p<0,05), this signifies that female has higher measured brain activity than male. However, this outcome is temporary because this study does not factor in the individual cognitive abilities based on assessment of puzzle completion, duration, or error while solving the puzzle. Analysis of cognition while solving puzzles gives an indication on the difference between left and right brain hemisphere, mainly on Gamma activity, and shows clear difference of brain activity between male and female.
