Alpha band (8-13Hz) electroencephalography (EEG) oscillations are central to cognition, but their generating mechanisms are poorly understood. Most laminar studies investigating origins of alpha oscillations rely on invasive animal intracranial recordings. To relate these findings to human alpha generation, non-invas...

OBJECTIVE
Magnetoencephalography (MEG) measures magnetic fields generated by current flow in neural assemblies, providing a non-invasive means to track brain function. In recent years, the MEG field has been revolutionised by a new class of field sensor called an Optically Pumped Magnetometer (OPM). OPMs are small, li...

Cross-frequency coupling describes interactions between neural ensembles operating at different frequency bands, and has been proposed to underlie coordination of brain activity over multiple temporal and spatial scales. Phase amplitude coupling (PAC) describes modulation of the amplitude of high-frequency oscillations...

Beta oscillations are a fundamental feature of brain activity, linked to long-range connectivity within canonical networks, inhibition of sensorimotor cortices and the maintenance of a stable sensorimotor state in situations where the external world is predictable. The importance of beta oscillations in brain function...

A mathematical model of brain tissue was developed that discovered that reducing the background signals to the brain cells reproduces the burst alterations seen in Parkinson’s disease, and simulations showed that strengthening the connections between brain cells can counteract this deficit, restoring healthy burst patt...
