Electroencephalography, or EEG, is the physiological method of choice to record the electrical activity generated by the brain via electrodes placed on the scalp surface. For faster application, electrodes are mounted in elastic caps similar to bathing caps, ensuring that the data can be collected ...
EEG (electroencephalography)measures the electrical activity of our brain via electrodes that are placed on the scalp. It tells us, from the surface measurements, how active the brain is. This can be useful for quickly determining how brain activity can change in response to stimuli, and can ...
An EEG is a test that detects the brain's electrical activity. Used to evaluate head injuries or neurological disorders, an EEG...
A counter argument is that these events are not characteristic of the seizures seen clinically in posttraumatic epilepsy or in other forms of acquired epilepsy. Furthermore, several types of brief, rhythmic activity can be recorded in the electroencephalogram (EEG) of animals and humans without ...
Some studies found problems with EEG fMRI from inconclusive results. In some patients, no changes or insignificant changes in BOLD signals occurred when electrical activity increased. One study that mapped brain waves of epileptic patients over a long period of time in an attempt to identify regions...
The main difference between an EEG and an EMG is what they're used to measure. While an EEG is used to measure electrical activity...
Although there is a great multiplicity of normal brain electrical activities, one can observe defined, relatively abrupt, transitions between apparently normal rhythms and clearly abnormal, higher amplitude, "epileptic" signals; transitions occur over tens of ms to many seconds. Transitional activity typi...
Fill in the blanks. The EEG reveals ___ (low/high) voltage, ___ EEG activity, and frequent ___ waves. What are the three common diseases of the breast that may be manifested as a lump in the breast? How does a physician distinguish one from another? Fill in the blanks...

A seizure is an episode of abnormal brain activity. A seizure can cause jerky muscle movements, loss of consciousness, or confusion. Recurrent means you have a seizure more than once. The cause of your seizures may not be known. Some common triggers are alcohol, drugs, lack of sleep, feve...
