*epileptic spike + wave discharges monitored with EEG*

-as of [24 SEPTEMBER 2024]–
.
-[electro-encephalography] is an ‘electro-physiological monitoring method’ to record ‘electrical activity’ of the ‘brain’-
.
(it is typically ‘non-invasive’, with the ‘electrodes’ placed along the ‘scalp’, although ‘invasive electrodes’ are sometimes used in specific applications)
(‘EEG’ measures ‘voltage fluctuations/ resulting from ionic current within the neurons of the ‘brain’)
(in ‘clinical contexts’, ‘EEG’ refers to the recording of the brain’s spontaneous electrical activity over a period of time, as recorded from multiple electrodes placed on the ‘scalp’)
(‘diagnostic applications’ generally focus on the ‘spectral content’ of ‘EEG’, that is, the type of ‘neural oscillations’ (popularly called “brain waves”) that can be observed in ‘EEG signals’)
(‘EEG’ is most often used to diagnose ‘epilepsy’, which causes ‘abnormalities’ in ‘EEG readings’)
(it is also used to diagnose ‘sleep disorders’, ‘coma’, ‘encephalopathies’, and ‘brain death’)
(‘EEG’ used to be a first-line method of diagnosis for tumors, stroke and other focal brain disorders, but this use has decreased with the advent of high-resolution anatomical imaging techniques such as magnetic resonance imaging (MRI) and ‘computed tomography’ (‘CT’))
(despite ‘limited spatial resolution’, ‘EEG’ continues to be a ‘valuable tool’ for ‘research’ and ‘diagnosis’, especially when ‘millisecond-range temporal resolution’ (not possible with ‘CT’ or ‘MRI’) is required)
(derivatives of the “EEG technique” include ‘evoked potentials’ (EP), which involves averaging the ‘EEG activity’ time-locked to the presentation of a ‘stimulus’ of some sort (‘visual’, ‘somatosensory’, or ‘auditory’))
.
(‘event-related potentials’ (‘ERPs’) refer to ‘averaged EEG responses’ that are ‘time-locked’ to more complex ‘processing’ of ‘stimuli’)
.
(his technique is used in…)
‘cognitive science’
‘cognitive psychology’
‘psycho-physio-logical research’
