  2. Electrocorticography - Wikipedia

    en.wikipedia.org/wiki/Electrocorticography

    The scalp EEG, while a valuable diagnostic tool, lacks the precision necessary to localize the epileptogenic region. ECoG is considered to be the gold standard for assessing neuronal activity in patients with epilepsy, and is widely used for presurgical planning to guide surgical resection of the lesion and epileptogenic zone.

  3. Electrogram - Wikipedia

    en.wikipedia.org/wiki/Electrogram

    An electroencephalogram (EEG) is an electrical recording of the activity of the brain taken from the scalp. An EEG can be used to diagnose seizures , sleep disorders , and for monitoring of level of anesthesia during surgery.

  4. Electroencephalography - Wikipedia

    en.wikipedia.org/wiki/Electroencephalography

    ERP studies can be conducted with relatively simple paradigms, compared with IE block-design fMRI studies; Relatively non-invasive, in contrast to electrocorticography, which requires electrodes to be placed on the actual surface of the brain. EEG also has some characteristics that compare favorably with behavioral testing:

  5. Electroencephalography functional magnetic resonance imaging

    en.wikipedia.org/wiki/Electroencephalography...

    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.

  6. 10–20 system (EEG) - Wikipedia

    en.wikipedia.org/wiki/10–20_system_(EEG)

    The "10" and "20" refer to the fact that the actual distances between adjacent electrodes are either 10% or 20% of the total front–back or right–left distance of the skull. For example, a measurement is taken across the top of the head, from the nasion to inion. Most other common measurements ('landmarking methods') start at one ear and end ...

  7. Electroneurogram - Wikipedia

    en.wikipedia.org/wiki/Electroneurogram

    An electroencephalogram (EEG) is a particular type of electroneurogram in which several electrodes are placed around the head and the general activity of the brain is recorded, without having very high resolution to distinguish between the activity of different groups of neurons.

  8. Intraoperative neurophysiological monitoring - Wikipedia

    en.wikipedia.org/wiki/Intraoperative...

    Intraoperative neurophysiological monitoring (IONM) or intraoperative neuromonitoring is the use of electrophysiological methods such as electroencephalography (EEG), electromyography (EMG), and evoked potentials to monitor the functional integrity of certain neural structures (e.g., nerves, spinal cord and parts of the brain) during surgery.

  9. EEG analysis - Wikipedia

    en.wikipedia.org/wiki/EEG_analysis

    EEG analysis is exploiting mathematical signal analysis methods and computer technology to extract information from electroencephalography (EEG) signals. The targets of EEG analysis are to help researchers gain a better understanding of the brain ; assist physicians in diagnosis and treatment choices; and to boost brain-computer interface (BCI ...
