Happiness is linked to reduced spontaneous gamma-band neural oscillations in the right precuneus. Using resting-state magnetoencephalography (MEG) in participants who completed happiness questionnaires, researchers found that gamma-band fractional amplitude of low-frequency fluctuation (fALFF) in the right precuneus was negatively associated with subjective happiness scores (partial correlation coefficient = -0.56). This suggests that subjective happiness has a neural electrical correlate in the precuneus, possibly mediated by reduced self-consciousness and heightened inhibitory interneuron activity.
