EEG is typically recorded during specific events of cognitive processing and comparisons are made to the EEG recorded during a resting or baseline period. An advantage of EEG is that the cognitive events can be relatively long, on the order of seconds or even minutes.

Using EEG is a way of exploring networks and functionality. Originally developed for examining patients with epilepsy, currently, it can be used for a wide variety of reasons, including investigating functional connectivity and functional brain networks, thus allowing the assessment of cognitive processes.
Can EEG be used in cognitive development research?
The electroencephalogram (EEG) is an efficient and relatively inexpensive method for the study of developmental changes in brain-behavior relations.
In this review, we highlight some of the challenges for using EEG in cognitive development research.
Can resting-state EEG measures detect cognitive decline in mild cognitive impairment?
Neurophysiological biomarkers of AD derived from EEG and FDG-PET, once characterized and … In this paper, we explore the utility of resting-state EEG measures as potential biomarkers for the detection and assessment of cognitive decline in mild cognitive impairment (MCI) and Alzheimer's disease (AD).

Overview
An electroencephalogram (EEG) is a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp.
Brain cells communicate via electrical impulses and are active all the time, even during asleep.
This activity shows up as wavy lines on an EEGrecording.
An EEG is one of the main diagnostic tests for e.
Results
Doctors trained to analyze EEGs interpret the recording and send the results to the doctor who ordered the EEG.
You might need to schedule an office appointment to discuss the results of the test.
If possible, bring along a family member or friend to the appointment to help you remember the information you're given.
Write down questions to ask your.
Risks
EEGsare safe and painless.
Sometimes seizures are intentionally triggered in people with epilepsy during the test, but appropriate medical care is provided if needed.
What are the advantages and disadvantages of EEG?
An advantage of EEG is that the cognitive events can be relatively long, on the order of seconds or even minutes.
For example, EEG power and coherence values can be obtained during multiple trials of a working memory task and during the encoding of stimuli for a later recall or recognition memory task.
What is a quantitative EEG?
The EEG discussed here is sometimes called “quantitative EEG” and is used for basic research on brain electrical activity during cognitive or affective processing.
The EEG signal recorded from the scalp is composed of multiple sine waves cycling at different frequencies.

Why It's Done
An EEG can find changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder.
An EEGmight also be helpful for diagnosing or treating:.
1) Brain tumors.
2) Brain damage from head injury.
3) Brain dysfunction that can have a variety of causes (encephalopathy).
4) Sleep disorders.
5) Inflamma.
