  2. Electroencephalography - Wikipedia

    en.wikipedia.org/wiki/Electroencephalography

    When an EEG shows interictal epileptiform discharges (e.g. sharp waves, spikes, spike-and-wave, etc.) it is confirmatory of epilepsy in nearly all cases (high specificity), however up to 3.5% of the general population may have epileptiform abnormalities in an EEG without ever having had a seizure (low false positive rate) [8] or with a very low ...

  3. Event-related potential - Wikipedia

    en.wikipedia.org/wiki/Event-related_potential

    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 ...

  4. 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.

  5. K-complex - Wikipedia

    en.wikipedia.org/wiki/K-complex

    A K-complex is a waveform that may be seen on an electroencephalogram (EEG).It occurs during stage 2 NREM sleep.It is the "largest event in healthy human EEG". [1] They are more frequent in the first sleep cycles.

  6. C1 and P1 - Wikipedia

    en.wikipedia.org/wiki/C1_and_P1

    The C1 and P1 (also called the P100) are two human scalp-recorded event-related brain potential (event-related potential (ERP)) components, collected by means of a technique called electroencephalography (EEG). The C1 is named so because it was the first component in a series of components found to respond to visual stimuli when it was first ...

  7. Pharmaco-electroencephalography - Wikipedia

    en.wikipedia.org/wiki/Pharmaco...

    The measures related the EEG changes to the common classes of psychoactive drugs—antidepressant, anxiolytic, antipsychotic, hallucinogen, deliriant, euphoriant, and mood stabilizer being the most frequent. For a time, the pharmaco-EEG profiles of different classes of drugs were actively used to identify active psychotropic agents.

    I took a nap in the office with Elemind, a headband that uses EEG technology to help you fall sleep. ... Alyssa's alpha oscillation - the red band of activity at 10Hz - shows wakefulness. When ...

  9. 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.
