EEG is a language all its own; here you'll learn the basic terminology of EEG waveforms, and how to communicate what you see

Aug 3, 2025 · Differentiating normal waveforms from abnormal patterns is essential for EEG to achieve high specificity and diagnostic value. EEG waveforms can be characterized by location, amplitude, …

Aug 4, 2025 · By recognizing which wave is dominant and where it’s occurring, neurologists can determine if the brain is functioning normally. EEG waves are analyzed by their amplitude (height), …

Oct 9, 2019 · The electroencephalogram (EEG) is the depiction of the electrical activity occurring at the surface of the brain. This activity appears on the screen of the EEG machine as waveforms of...

These electrical signals show up as waveforms on the EEG and can be categorized by their location, size, speed, shape, pattern, symmetry, and response to activity. Most of the time, these waveforms …

Jun 14, 2024 · A wave in EEG terms is defined by the change in potential difference between two electrodes. This signal's shape, generated by oscillating potential differences, is referred to as its …

The EEG is examined for asymmetries between the 2 hemispheres (suggesting a structural disorder), for excessive slowing (appearance of 1- to 4-Hz, 50- to 350-muV delta waves, as occurs in …

By recording brain wave patterns throughout sleep cycles, an EEG can help diagnose conditions such as sleep apnea or narcolepsy. This provides valuable information for developing targeted interventions.

Learn the basics of how electrical signals in the brain are converted into the signal we see on EEG

There are five major brain waves distinguished by their different frequency ranges. These include: alpha, theta, beta, delta and gamma. The EEG recording electrodes and their proper function are crucial for …
