Long-term or "continuous" video-electroencephalography (EEG) monitoring is a diagnostic technique commonly used in patients with epilepsy.It involves the long-term hospitalization of the patient, typically for days or weeks, during which brain waves are recorded via EEG and physical actions are continuously monitored by video.
Electroencephalography data can be viewed as a qualitative wave form, or it can be further processed through analytical procedures to produce quantitative electroencephalography (qEEG). [2] If qEEG data is mapped from multiple parts of the brain then it is a topographic qEEG (also known as brain electrical activity mapping or BEAM).
Wearable EEG aims to provide small EEG devices which are present only on the head and which can record EEG for days, weeks, or months at a time, as ear-EEG. Such prolonged and easy-to-use monitoring could make a step change in the diagnosis of chronic conditions such as epilepsy, and greatly improve the end-user acceptance of BCI systems. [123]
An EEG is a procedure that records the brain's electrical activity. This is done by attaching electrodes to the scalp. This test is done to see how medicine is affecting the electrical problems in the brain. Medication may not be required to be taken indefinitely. Children may be taken off medicine if no seizures are experienced for 1 to 2 years.
The same is done for the odd-numbered electrodes on the left side, to complete the full circumference. Measurement methods for placement of the F3, F4, P3, and P4 points differ. If measured front-to-back (Fp1-F3-C3-P3-O1 and Fp2-F4-C4-P4-O2 montages), they can be 25% "up" from the front and back points (Fp1, Fp2, O1, and O2).

Most children don't say their first word until the age of 1 but Helena Kordaé's son might be an exception.
This procedure may be performed either under general anesthesia or under local anesthesia if patient interaction is required for functional cortical mapping. Electrodes are then surgically implanted on the surface of the cortex, with placement guided by the results of preoperative EEG and magnetic resonance imaging (MRI). Electrodes may either ...
