Why do people with schizophrenia hear voices in their heads?
The problem with “voices in the head” is that their nature is unclear. Voices sound without any external stimuli. And, curiously, it feels like the voices of other beings that somehow get into the “head” of a person with schizophrenia. What is the true cause of this disorder?
Consciousness and the brain are extremely complex elements, both to study and to try to “improve” anything about them. The more I study materials and write articles about productivity, the more I understand that its true meaning is not so much acceleration as sensing a certain “corridor of normal conditions” in which the brain will work as efficiently as possible.

Auditory hallucinations, schizophrenia, causes
Auditory hallucinations are the result of abnormalities in two brain processes: the inability to suppress self-generated sounds and the sound of those sounds being heard more intensely than they should sound. This is the conclusion new researchconducted by Xing Tian of New York University in Shanghai, China, and colleagues.
Patients with some mental disorders, including schizophrenia, often hear voices in the absence of sound. Patients are unable to separate their own thoughts from external voices, resulting in a decreased ability to recognize thoughts as being generated by their own brain. Moreover, schizophrenia may be based not only on brain disorders, but also autoimmune diseasesdestroying the blood-brain barrier.
In the new study, researchers conducted electroencephalogram (EEG) experiments, measuring the brain waves of twenty patients diagnosed with schizophrenia who had auditory hallucinations and twenty patients diagnosed with schizophrenia who had never experienced such hallucinations.
Norm and pathology
Typically, when people prepare to speak, their brains send out a signal known as a “follow-up” that suppresses the sound of our thinking voice.
A new study found that when patients with auditory hallucinations prepared to utter a syllable, their brains not only failed to suppress these internal sounds, but also showed an enhanced “efferent copy” response, maintaining the sound of internal thoughts other than the intended syllable.
The authors conclude that disruptions in these two processes likely contribute to the occurrence of auditory hallucinations and that correcting these mechanisms may lead to new treatments for such hallucinations.
People who suffer from auditory hallucinations may “hear” sounds without external stimuli. New research suggests that disruption of functional connections between the motor and auditory systems in the brain leads to a loss of the ability to distinguish fiction from reality.
Conclusion of the authors of the article
Well, groping for the biomechanisms on which the foundation of our psyche rests is already not bad. The better we understand the brain, its work and functions, the more space opens up in order to increase our skills, abilities and knowledge.
