Stimulation modalities of Audio-visual Entrainment (AVE), cranio-electro stimulation (CES) and transcranial DC stimulation (tDCS) have been in clinical use for several decades.
Since the discovery of photic driving by Adrian and Matthews in 1934, much has been discovered about the benefits of brainwave entrainment (BWE) or audio-visual entrainment (AVE), as it is commonly known today. The first clinical applications of AVE are the credit of Sidney Schneider who developed the first photic stimulation device called the Brain Wave Synchronizer in 1958 and prompted the first research. AVE affects cerebral blood flow, neurotransmitters, dissociative states and brainwave activity. Research on the effectiveness of AVE in promoting relaxation, cognition and hypnotic induction, treating ADD, PMS, SAD, PTSD, migraine headache, chronic pain, anxiety, depression and episodic memory is now available.
As far back as the first century, the Greeks and Romans used the electric eel, a variety of the “torpedo fish” for electrical stimulation. Current interest in CES was initiated by Robinovitch, who, in 1914, made the first claim for electrical treatment of insomnia. In 1958, the book Electro-Sleep inspired research in Europe and in Eastern Block countries, as well as in South America, Asia and finally the US. Roughly 130 studies have been published on CES. Most of the roughly 130 studies have shown CES as a reliable method to reduce anxiety, depression, pain, improve sleep, and improve cognition and IQ.
In 43 to 48 AD, Scribonius Largus, the physician of Roman emperor Claudius, observed that placing a large torpedo fish (electric eel) over the scalp of a patient suffering with headache, elicited a sudden transient stupor with pain relief. A major advantage of tDCS is that the cortical activity over a specific site on the brain may be enhanced or suppressed, much like NF. Dozens of studies on, tDCS have been published to date.
All maladies are the result of dysarousal on a physical or cortical level. Stimulation technologies can restabilize one’s arousal.
