neural oscillations
Definition
Neural oscillations refers to rhythmic fluctuations in electrical activity generated by the summed activity of pyramidal neurons in the brain, measured through techniques such as electroencephalography (EEG). Beta oscillations (15–40 Hz) present particular challenges for detection and interpretation, as they are less sustained and have lower amplitudes than lower-frequency rhythms, and can be artifactually produced by non-sinusoidal properties of more prominent lower-frequency oscillations. Genuine neural oscillations can be isolated through algorithmic approaches that control for confounding lower-frequency rhythms, allowing investigation of their functional modulation during cognitive tasks.

Neural Oscillations and Cognitive Load
The characteristics of neural oscillations, particularly beta bursts, are functionally modulated during working memory tasks. Beta burst properties including amplitude, duration, peak frequency, and rate vary with task parameters.
