Slow waves eeg
WebbThere exists a paucity of data in the EEG literature on characteristics of “atypical” interictal epileptiform discharges (IEDs), including sharp slow waves (SSWs). This article aims to … WebbIndeed, EEG signals change dramatically during sleep and show a transition from faster frequencies to increasingly slower frequencies such as alpha waves. In fact, different sleep stages are commonly characterized by their spectral content. Consequently, neural oscillations have been linked to cognitive states, such as awareness and consciousness.

Delta waves typically have a frequency of 1 to 4 hertz (cycles per second) and are the largest in amplitude out of the five main types of brain waves. Slow delta …
WebbHowever, how the two conditions are pathologically connected is not completely understood. Similar neurophysiological abnormalities have been reported in both DM and MDD, including elevated electroencephalographic (EEG) activity in low-frequency slow waves and increased latency and/or reduced amplitude of event-related potentials.

WebbEEG and EMG signals, typically sampled at >100 Hz, are segmented arbitrarily into epochs of equal duration (usually 2–10 seconds), and each epoch is scored as wake, slow-wave sleep (SWS), or rapid-eye-movement sleep (REMS), on the basis of visual inspection.
