Computer-Assisted Interpretation of the EEG Background Pattern: A Clinical Evaluation
Computer-assisted interpretation of the EEG background pattern can bring consistency to reviewing and improve efficiency and inter-rater agreement in routine reviews.

Computer assisted interpretation of the human EEG: improving diagnostic efficiency and consistency in clinical reviews
Algorithms were developed to automatically characterize five common EEG background properties: the posterior dominant peak frequency; reactivity; anterior-posterior gradients; symmetry; and the presence or absence of diffuse slow-wave activity and an intuitive and efficient technique was also developed for the automated detection of inter-ictal epileptiform discharges.

Measurements of EEG Alpha Peak Frequencies Over the Lifespan: Validating Target Ranges on an In-Clinic Platform
In-clinic measures of peak EEG frequency corroborate the age-related trends of published research taken over the last several decades and IAF, confirming that IAF is a stable trait, making it useful for within-person longitudinal tracking.
Standardized Computer-based Organized Reporting of EEG: SCORE
The purpose was to create a computer‐based system for EEG assessment and reporting, where the physicians would construct the reports by choosing from predefined elements for each relevant EEG feature, as well as the clinical phenomena (for video‐EEG recordings).
Symbolic Entropy of the Amplitude rather than the Instantaneous Frequency of EEG Varies in Dementia
The results suggest that the EEG dynamics which relates to either cognitive functions or the underlying pathologies of dementia are embedded within the dynamics of the amount of but not the interval between each synchronized firing of adjacent cerebral neurons.

Electrophysiologic function in the healthy, extremely old
The effects of healthy aging on clinical electrophysiologic tests of cerebral function are highlighted and three CEEGFA variables studied all demonstrated a significant change with age, most marked above age 80 years.
Age‐related differences in brain electrical activity of healthy subjects
A combined neurophysiological (electroencephalographic [EEG] and sensory evoked potential) and neuropsychological investigation was performed on 63 healthy men ranging in age from 30 to 80 years.

Some of the unusual patterns that can be encountered on the EEG are described briefly and included are alpha squeak, retained alpha, alpha-delta sleep, unilateral decrease in reactivity of alpha activity, and extreme spindles.

Interobserver variability in EEG interpretation
There is considerable variability in EEG interpretation, and this variability is influenced by specific reader characteristics, according to a random sample of active electroencephalographers in the United States.
