Potential mechanisms and functional significance of aperiodic neural activity (opens in new tab)

Human and animal electrophysiology often looks noisy and unstructured. While some clearer features exist in the form of bursty oscillations and event-related potentials, recent methodological developments have helped to uncover surprising structure in what otherwise looks like noise. This signal, referred to as aperiodic activity, has received substantial recent attention, examining its physiological generators and relationship to behaviour, cognition, development, ageing and disease. Here we...
