Researchers typically collect data from a small sample of participants and hope that other researchers replicate the results to validate inferences about the general population. Although EEG has been a useful clinical and scientific tool, its applications have been constrained because recording of EEG data is time-consuming and requires laboratories equipped with expensive EEG equipment.

For example, clinicians have used EEG to understand several illnesses, including epilepsy and sleep disorders engineers have used EEG to develop wheelchairs that respond to brain states and psychologists have used EEG to track the temporal flow of information through the sensory systems and identify neural correlates of psychological processes. We discuss our findings in terms of their relevance to attentional processes and brain-based models of emotional well-being and aging.įor many decades, electroencephalography (EEG) has been used effectively for different purposes in a variety of fields. Unlike previous age-related EEG studies that were limited by sample size and restricted age ranges, our work highlights the advantage of using large, representative samples to address questions about developmental brain changes. Our results replicate several previous age- and sex-related findings and show how some previously observed changes during childhood extend throughout the lifespan. Finally, our analysis of α asymmetry revealed greater relative right frontal activity. We also found a gradual, year-by-year slowing of the peak α frequency with increasing age. We found an overall age-related shift in band power from lower to higher frequencies, especially for females. We found that EEG power changed as a function of age, and that the age-related changes depended on sex and frequency band. Here, we report age-related changes in EEG power at a fine chronological scale for δ, θ, α, and β bands, as well as peak α frequency and α asymmetry measures for both frontal and temporoparietal sites.

Using the Muse, a portable and wireless four-channel EEG headband, we obtained EEG recordings from 6029 subjects 18–88 years in age while they completed a category exemplar task followed by a meditation exercise. However, the amount of time needed to gather EEG data means that most laboratory studies use relatively small sample sizes. For decades, electroencephalography (EEG) has been a useful tool for investigating the neural mechanisms underlying human psychological processes.
