Proposed Mechanism of Action
The exact mechanism of action of CES remains unclear but it is proposed that CES reduces the stress that underpins many emotional disorders. The proposed mechanism of action for CES is that the pulses of electric current increase the ability of neural cells to produce serotonin, dopamine DHEA endorphins and other neurotransmitters stabilizing the neurohormonal system.
It has been proposed that during CES, an electric current is focused upon the hypothalamic region; during this process, CES electrodes are placed on the ear at the mastoid, near to the face. Computer modeling suggest that current of similar magnitudes maybe induced in both cortical and sub-cortical regions. The prediction that CES induced current intensities in the sub-cortical structures are not sufficiently decreased from the cortical structures is potentially clinically meaningful.
It has been suggested that the current results in an increase of the brain's levels of serotonin, norepinephrine, and dopamine, and a decrease in its level of cortisol. After a CES treatment, users are in an "alert, yet relaxed" state, characterized by increased alpha and decreased delta brain waves as seen on EEG.

“He [Roosevelt] has made some speeches that indicate that he is going quite beyond anything that he advocated when he was in the White House, and has proposed a program which is absolutely impossible to carry out except by a revision of the Constitution.”
—William Howard Taft (1857–1930)
“When one of us dies of cancer, loses her mind, or commits suicide, we must not blame her for her inability to survive an ongoing political mechanism bent on the destruction of that human being. Sanity remains defined simply by the ability to cope with insane conditions.”
—Ana Castillo (b. 1953)
“Rash actions are seldom committed in isolation. With the first rash action we always do too much. So we usually go on to commit a second one—and then we do too little.”
—Friedrich Nietzsche (1844–1900)
