Summary: A recent study demonstrates that two damaged mental processes, including a failed attempt to suppress self-generated sounds and an active response to domestic noises, may be the cause of auditory hallucinations in schizophrenia. In contrast to those without hallucinations, the study found that those with hallucinations had a “broken” principle discharge and a stronger response to unforeseen sounds.
These studies point to potential future remedies for auditory hallucinations that could pin these troubled processes.
Important Information:
- A defective destruction of self-generated sound causes auditory hallucinations.
- Patients who had delusions had an active brain reaction to unexpected sounds.
- These behaviors could lead to novel therapies for audio illusions.

A “broken” principle release that fails to control self-generated sound and a “noisy” efference version that makes the brain hear these noises more intensely than it should are probably the causes of hearing hallucinations.
That is the realization of a new research published October 3rd , in the open-access journal , PLOS Biology , by Xing Tian, of New York University Shanghai, China, and associates.
Individuals with certain emotional disorders, including dementia, generally hear voices in the emergence of sound. Patients may struggle to separate between their own thoughts and physical voices, leading to a lessening ability to recognize thoughts as self-generated.
In the new study, researchers conducted electroencephalogram ( EEG ) measurements of the brain waves of twenty patients with auditory hallucinations and twenty patients with schizophrenia who had never had such hallucinations.
In general, when people are preparing to communicate, their neurons send a message known as” principle release” that suppresses the tone of their own words.
However, the latest study found that when auditory hallucinations patients were preparing to talk a syllable, their brains not only failed to control these domestic sounds but also had an increased “efference copy” response to domestic sounds other than the organized syllable.
The artists come to the conclusion that the impairments of these two processes, which are likely to be a cause of hearing hallucinations, could be used to treat such hallucinations in the future.
The writers add that “people who experience auditory hallucinations is hear” sounds without using outside stimuli. A new study suggests that people who have poor useful connections between their brains ‘ motor and audio devices lose the ability to differentiate between “fantastic” and “real” things.
