Brief meditation increases theta brainwave power in the frontal region, which is linked to attention and relaxation. Analyzing EEG data from the PEM-43 dataset, theta power rose during meditation (52.4 µV2·Hz) and dropped afterward (45 µV2·Hz) compared to resting state. Frontal channels showed the highest mean theta power (Fp1: 59.5 µV2·Hz, Fz: 59.4 µV2·Hz), while central and posterior regions had lower activity. Statistical tests confirmed a significant increase during meditation, suggesting brief meditation can measurably modulate cognitive engagement and relaxation.
