EEG is a non-invasive technique that can measure brain activity. The neural activity generates electrical signals that are recorded by EEG electrodes placed on the scalp. When an individual is engaged in performing a cognitive task, brain activity changes and these changes can be recorded on the EEG graph. Therefore, it is a powerful tool for cognitive scientist aiming to better understand the neural correlates associated with different aspects of cognition, which will ultimately help them...

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that has shown initial therapeutic effects in several neurological conditions. The main mechanism underlying these therapeutic effects is the modulation of cortical excitability. Therefore, online monitoring of cortical excitability would help guide stimulation parameters and optimize its therapeutic effects. In the present article we review the use of a novel device that combines simultaneous tDCS and...
FAQs
Scalp electrodes register voltage fluctuations associated with synchronized neuronal activity. Reviewers then examine the resulting recording for characteristic waveforms and background rhythms, using signal processing and visual analysis to separate meaningful patterns from noise and artifacts. This connection between biological activity and measurable voltage is central to interpreting whether a tracing contains patterns relevant to neurological care.
Electrode placement and recording conditions directly affect how confidently a tracing can be interpreted. Placement determines where scalp voltage fluctuations are sampled, while the recording conditions influence the quality of the captured signal. For Clinical EEG Review, attention to these factors helps reviewers judge whether an observed waveform reflects brain activity or a recording-related problem, improving the reliability of subsequent interpretation.
Reviewers distinguish potentially meaningful patterns from artifacts and noise by examining waveform characteristics alongside normal background rhythms. Signal processing can assist this separation, while visual analysis provides contextual inspection of the recording. This step matters because a waveform that appears unusual may reflect recording interference rather than altered brain electrical activity, affecting how the tracing is interpreted.
Signal processing and visual analysis contribute different perspectives on the same recording. Processing helps distinguish characteristic waveforms from artifacts, noise, and normal background rhythms, while visual review supports direct inspection of those features in context. Their combination strengthens pattern recognition and links human interpretation with computational approaches used to develop automated detection tools.
A reliable workflow begins with appropriately placed scalp electrodes and attention to recording conditions. The recorded voltage fluctuations are then examined through signal processing and visual analysis, with the reviewer comparing characteristic waveforms against artifacts, noise, and normal background rhythms. The final interpretation connects these observations to neurological evaluation, rather than treating an isolated waveform as meaningful without context.
Clinical EEG review can inform assessment of seizures and epilepsy, as well as sleep-related abnormalities and diffuse brain dysfunction. These uses depend on recognizing patterns within the recording and interpreting them in a neurological-care context. The same review process therefore supports both focused evaluation of seizure-related activity and broader assessment of abnormal or altered brain function.
In bioengineering, the review process connects biopotential measurement with sensor design, signal processing, and clinical interpretation. This relationship can guide improved recording systems and the development of automated detection tools, while keeping their purpose tied to patterns observed in patient EEG data. It also shows how engineering choices, such as electrode placement and recording conditions, influence the usefulness of neurological measurements.
