A gamma wave or gamma rhythm is a pattern of neural oscillation in humans with a frequency between 30 and 100 Hz, the 40 Hz point being of particular interest. [1] Gamma waves with frequencies between 30 and 70 hertz may be classified as low gamma , and those between 70 and 150 hertz as high gamma .
Traditional classification of the frequency bands, that are associated to different functions/states of the brain and consist of delta, theta, alpha, beta and gamma bands. . Due to the limited capabilities of the early experimental/medical setup to record fast frequencies, for historical reason, all oscillations above 30 Hz were considered as high frequency and were difficult to investigate.
Other frequency bands are: delta (1–4 Hz), theta (4–8 Hz), beta (13–30 Hz), low gamma (30–70 Hz), [15] and high gamma (70–150 Hz) frequency bands. Faster rhythms such as gamma activity have been linked to cognitive processing. Indeed, EEG signals change dramatically during sleep.
By 1900 application of high-frequency current to the body was used experimentally to treat a wide variety of medical conditions in the quack medical field of electrotherapy. In 1899 Austrian chemist von Zaynek determined the rate of heat production in tissue as a function of frequency and current density, and first proposed using high-frequency ...
Terahertz waves lie mostly at the far end of the infrared band, the longest ones in the microwave band. Terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency [1] (THF), T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the International Telecommunication Union-designated band of frequencies from 0.1 to 10 ...
A medical intuitive is an alternative medicine practitioner who claims to be able to use their intuitive abilities to find the cause of a physical or emotional condition through the use of insight rather than modern medicine. [1] Other terms for such a person include medical clairvoyant or medical psychic.
The activity of this "pure ego" can be discovered by a "higher intuition". [ 2 ] [ note 1 ] [ clarification needed ] According to Michael Whiteman, Fichte's philosophical system "is a remarkable western formulation of eastern mystical teachings (of which he seems to have had no direct knowledge)."
A violet ray is an antique medical appliance used during the early 20th century to discharge in electrotherapy. Their construction usually featured a disruptive discharge coil with an interrupter to apply a high voltage, high frequency, low current to the human body for therapeutic purposes.
