Allan H. Frey (born 1935) is an American neuroscientist known for his research and writing during the Cold War on the nature of the microwave auditory effect, also called the "Frey effect". He worked at General Electric's Advanced Electronics Center at Cornell University. In 1975, Frey published a study in the Annals of the New York Academy of Sciences stating that microwaves "with certain modulations" could cause leakage in the blood-brain barrier, with possibly lethal consequences. After publishing this, he was effectively silenced by the United States government. Frey currently lives in Annapolis, Maryland.[1]
