Lifespan associated global patterns of coherent neural communication

" We observed a significant age-related decline in peak alpha frequency (PAF) at the sensor level as well as increase in broadband beta power in a healthy cohort consisting of 650 human participants from the CAMCAN repository (Fig 1). Out of all sensor specific spectral features such as frequency and amplitude of oscillations in narrowband and broadband, PAF and beta power varied exclusively with age in opposite ways (Fig 1). Subsequently we could track the global subspace that sculpts the alpha and beta topographies, and their corresponding overlap over lifespan. Interestingly the angular separation between the alpha and beta topographies increase with age indicative of segregation of underlying generators over lifespan (Fig 2)." {Credits 1}
