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 ...

An EEG recording setup using the 10-10 system of electrode placement. EEG is the gold standard diagnostic procedure to confirm epilepsy . The sensitivity of a routine EEG to detect interictal epileptiform discharges at epilepsy centers has been reported to be in the range of 29–55%. [ 8 ]

Clinical neurophysiology, is a broader field that includes EEG, intraoperative monitoring, nerve conduction studies, EMG and evoked potentials. [10] The American Board of Psychiatry and Neurology provides certification examination in clinical neurophysiology. The American Board of Electrodiagnostic Medicine provides certification in EDX ...
Quantification and analyses. In the beginning the EEG recordings were made on paper and changes measured visually, scored by ruler and calipers. By the 1960s, electronic analyzers of 10 second epochs measured changes in "power." Digital computer methods using period analysis, power spectral density, and amplitude analyses followed.
Cordance, a measure of brain activity, is a quantitative electroencephalographic (QEEG) method, developed in Los Angeles in the 1990s. [1] [2] It combines complementary information from absolute (the amount of power in a frequency band at a given electrode) and relative power (the percentage of power contained in a frequency band relative to the total spectrum) of EEG spectra.
English: EEG electrode positions in the 10-10 system using modified combinatorial nomenclature as presented by Klem, Lüders, Jasper, & Elger (1999). The electrode sites are colour-coded according to the lobes of the brain which their labels (F, C, P, O, and T) represent.
