This research indicates that control is rapid, requires minimal training, balancing signal fidelity and level of invasiveness. [note 1] Signals can be either subdural or epidural, but are not taken from within the brain parenchyma. Patients are required to have invasive monitoring for localization and resection of an epileptogenic focus.
Fidelity is therefore a measure of the realism of a model or simulation. [4] Simulation fidelity has also been described in the past as "degree of similarity". [5] In quantum mechanics and optics, [6] the fidelity of a field is calculated as an overlap integral of the field of interest with a reference or target field.
Salience (also called saliency, from Latin saliō meaning “leap, spring” [1]) is the property by which some thing stands out.Salient events are an attentional mechanism by which organisms learn and survive; those organisms can focus their limited perceptual and cognitive resources on the pertinent (that is, salient) subset of the sensory data available to them.
Signal integrity or SI is a set of measures of the quality of an electrical signal. In digital electronics , a stream of binary values is represented by a voltage (or current) waveform. However, digital signals are fundamentally analog in nature, and all signals are subject to effects such as noise , distortion , and loss.
Perceptual control theory has not been widely accepted in mainstream psychology, but has been effectively used in a considerable range of domains [57] [58] in human factors, [59] clinical psychology, and psychotherapy (the "Method of Levels"), it is the basis for a considerable body of research in sociology, [60] and it has formed the ...
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]

The N400 is a component of time-locked EEG signals known as event-related potentials (ERP). It is a negative-going deflection that peaks around 400 milliseconds post-stimulus onset, although it can extend from 250-500 ms, and is typically maximal over centro-parietal electrode sites.
