The EEG has been used for many purposes besides the conventional uses of clinical diagnosis and conventional cognitive neuroscience. An early use was during World War II by the U.S. Army Air Corps to screen out pilots in danger of having seizures; [116] long-term EEG recordings in epilepsy patients are still used today for seizure prediction.
This reduction in blood glucose led to double the occurrence of spike-and-wave activity. Similar to the insulin effect, overnight fasting, where blood glucose levels were reduced by 35% also showed this double in occurrence. This model concludes that low glucose levels could be a potential trigger for absence seizures, and could be an ...
EEG-fMRI (short for EEG-correlated fMRI or electroencephalography-correlated functional magnetic resonance imaging) is a multimodal neuroimaging technique whereby EEG and fMRI data are recorded synchronously for the study of electrical brain activity in correlation with haemodynamic changes in brain during the electrical activity, be it normal function or associated with disorders.
A paper published in 2023 showed that burst suppression and epilepsy may share the same ephaptic coupling mechanism. [6] When inhibitory control is sufficiently low, as in the case of certain general anesthetics such as sevoflurane (due to a decrease in the firing of interneurons [7]), electric fields are able to recruit neighboring cells to fire synchronously, in a burst suppression pattern.
Partial epilepsy [14] is the common intractable epilepsy and the partial seizure is difficult to locate.Treatment for such epilepsy is limited to attachment of vagus nerve stimulator. Epilepsy surgery is the cure for partial epilepsy provided that the brain region generating seizure is carefully and accurately removed.
Richard Caton discovered electrical activity in the cerebral hemispheres of rabbits and monkeys and presented his findings in 1875. [4] Adolf Beck published in 1890 his observations of spontaneous electrical activity of the brain of rabbits and dogs that included rhythmic oscillations altered by light, detected with electrodes directly placed on the surface of the brain.

Epilepsy, a brain disorder that causes seizures, is one of the most common conditions that affects the brain. According to the Centers for Disease Control and Prevention (CDC), about 3.4 million ...
The EEG proved to be a useful source in recording brain activity over the ensuing decades. However, it tended to be very difficult to assess the highly specific neural process that are the focus of cognitive neuroscience because using pure EEG data made it difficult to isolate individual neurocognitive processes. Event-related potentials (ERPs ...
