Scientists from Yale University have found out why auditory hallucinations are experienced not only by the mentally ill, but also by absolutely healthy people.. The study was published in the journal Science.

To do this, scientists used a technique developed in the 1890s that causes auditory hallucinations.. During the experiment, four groups of people with auditory hallucinations (with and without a diagnosed disease) and without them (also with and without a diagnosis) had to look at light and sound signals several times.. During this, scientists scanned their brains.. Respondents had to recognize a tone that was difficult to hear.

It turned out that the cause of hallucinations is an imbalance between a person's expectations about the environment and the information received with the help of the senses..

After the experiment, many participants reported that they heard a sound during the light signal, although there was no tone signal at that time.. Most of the respondents who " Based on this, scientists concluded that the same processes occur in the brain of people who hear “voices” that were recorded during the scan, when the respondents “heard” the signal.
