Delta and Alpha Waves: Types of brain waves measured by EEG; delta waves are associated with deep sleep, while alpha waves are linked to relaxed, calm states. Machine Learning (ML): A subset of ...
Conclusions Systematic differences in EEG recordings were found between three urban areas ... and conversely excitement or agitation when delta waves are suppressed; θ (4–8 Hz), indicating deep ...
