Aspartame is recommended as a food additive after review by FDA on scientific data regarding the safety of aspartame in food and the conclusions was that it is safe for the general population to consume except for people with a rare hereditary disease known as phenylketonuria (PKU) unable to metabolize phenylalanine, a component of aspartame.
As of 2014, in response to citizen Betty Martini's petition mentioned here and Paul Stoller MD's petition mentioned here, FDA found no credible evidence for brain effects after reviewing aspartame safety which matches aspartame safety review data from various other regulatory agencies.
Referring to a report on MKULTRA program employed by CIA to counter perceived Soviet and Chinese advances in brainwashing techniques, aspartame was not one of the substances disclosed to cause hallucinogenic effect. The known halluciongens tested were LSD and quinuclidinyl benzilate, code-named BZ. The other experiments involved chemicals such as heroin, morphine, temazepam (used under code name MKSEARCH), mescaline, psilocybin, scopolamine, marijuana, alcohol, sodium pentothal, barbiturate IV and amphetamine IV in each arm.
Someday it may be possible to stimulate electronically or chemically a specific network of neurons to cause specific sounds or sights of the experimenter’s choosing to emerge in a person's consciousness. But this is not possible today. Even if it were possible, it would not necessarily follow that a person would obey a command to assassinate the president just because he heard a voice telling him to do so. Hearing voices is one thing. Feeling compelled to obey them is quite another.
If we define mind control as the successful control of the thoughts and actions of another without his or her consent, mind control exists only in fantasy. Unfortunately, that does not mean that it will always be thus.
Extremely low frequency electromagnetic fields (EMF) are known to surround home appliances as well as high-voltage electrical transmission lines and transformers. Evidence of health effects such as influence on brain from EMF is inconclusive referring to Amir Raz, assistant professor of clinical neuroscience at Columbia University.
Evidence of health effects from EMF, including their influence on the brain, is inconclusive, and the probability that EMF exposure is a genuine health hazard is currently small. Nevertheless, exposure to high levels of nonionizing energy, such as at radio wave frequencies, can damage the structure and function of the nervous system. For example, microwave frequencies below 3,000 megahertz can penetrate the outer layers of the skin, be absorbed in the underlying tissues, and result in all of the known biological effects of heating, including burns, cataracts, and possibly death.
