  2. P50 (neuroscience) - Wikipedia

    en.wikipedia.org/wiki/P50_(neuroscience)

    In electroencephalography, the P50 is an event related potential occurring approximately 50 ms after the presentation of a stimulus, usually an auditory click. [1] The P50 response is used to measure sensory gating , or the reduced neurophysiological response to redundant stimuli.

  3. Event-related potential - Wikipedia

    en.wikipedia.org/wiki/Event-related_potential

    ERPs can be reliably measured using electroencephalography (EEG), a procedure that measures electrical activity of the brain over time using electrodes placed on the scalp. The EEG reflects thousands of simultaneously ongoing brain processes. This means that the brain response to a single stimulus or event of interest is not usually visible in ...

  4. Electroencephalography - Wikipedia

    en.wikipedia.org/wiki/Electroencephalography

    Electroencephalography (EEG) [1] is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex . [ 2 ]

  5. EEGLAB - Wikipedia

    en.wikipedia.org/wiki/EEGLAB

    EEGLAB is a MATLAB toolbox distributed under the free BSD license for processing data from electroencephalography (EEG), magnetoencephalography (MEG), and other electrophysiological signals. [ 1 ] [ 2 ] Along with all the basic processing tools, EEGLAB implements independent component analysis (ICA), time/frequency analysis, artifact rejection ...

  7. Evoked potential - Wikipedia

    en.wikipedia.org/wiki/Evoked_potential

    The sweep technique is a hybrid frequency domain/time domain technique. [16] A plot of, for example, response amplitude versus the check size of a stimulus checkerboard pattern plot can be obtained in 10 seconds, far faster than when time-domain averaging is used to record an evoked potential for each of several check sizes. [16]

  8. EEG microstates - Wikipedia

    en.wikipedia.org/wiki/EEG_microstates

    EEG microstates are transient, patterned, quasi-stable states or patterns of an electroencephalogram.These tend to last anywhere from milliseconds to seconds and are hypothesized to be the most basic instantiations of human neurological tasks, and are thus nicknamed "the atoms of thought". [1]

  9. 10–20 system (EEG) - Wikipedia

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

    Electrode locations of International 10-20 system for encephalography recording. The 10–20 system or International 10–20 system is an internationally recognized method to describe and apply the location of scalp electrodes in the context of an EEG exam, polysomnograph sleep study, or voluntary lab research.
