In skin conductance, an electrodermograph enforces an invisible current across the skin and measures how easily it travels through the skin. When anxiety raises the level of sweat in a sweat duct, conductance increases. Skin conductance is measured in microsiemens (millionths of a siemens). In skin capacity, a therapist places an active electrode over an active site (e. g., the palmar surface area of the hand) and a recommendation electrode over a reasonably non-active site (e. g., lower arm). Skin capacity is the voltage that establishes between eccrine sweat glands and internal tissues and is measured in millivolts (thousandths of a volt).

Skin resistance is determined in k (countless ohms).  This Site  use electrodermal biofeedback when treating stress and anxiety conditions, hyperhidrosis (extreme sweating), and stress. Electrodermal biofeedback is utilized as an adjunct to psychotherapy to increase customer awareness of their feelings. In addition, electrodermal steps have long served as one of the central tools in polygraphy (lie detection) because they show modifications in anxiety or psychological activation. An electroencephalograph (EEG) determines the electrical activation of the brain from scalp sites situated over the human cortex. The EEG shows the amplitude of electrical activity at each cortical site, the amplitude and relative power of numerous wave forms at each website, and the degree to which each cortical site fires in conjunction with other cortical websites (coherence and symmetry).

The EEG records both excitatory postsynaptic capacities (EPSPs) and repressive postsynaptic potentials (IPSPs) that mainly occur in dendrites in pyramidal cells located in macrocolumns, a number of millimeters in size, in the upper cortical layers. Neurofeedback monitors both sluggish and fast cortical capacities. Slow cortical potentials are progressive modifications in the membrane potentials of cortical dendrites that last from 300 ms to numerous seconds. These potentials consist of the contingent negative variation (CNV), readiness potential, movement-related capacities (MRPs), and P300 and N400 potentials. Quick cortical capacities vary from 0. 5 Hz to 100 Hz. The main frequency ranges consist of delta, theta, alpha, the sensorimotor rhythm, low beta, high beta, and gamma.
