This study brings together the findings obtained previously. Many scientists noticed that when the patient is hallucinating, the neurons of the brain that are responsible for the transmission of audio signals intensified, despite the lack of sound waves to run such a reaction.
Another study showed that if during that appeared as hallucinations occurred "real" sounds, the brain does not respond to any one nor the other. These studies point to the suppression of brain signals.
Analyzing these works, a biological psychologist Kenneth Hugdahl of the University of Bergen in Norway found a way at the same time over-stimulation and "extinction" brain signals. The obtained results help explain why people with schizophrenia "leave" a hallucinatory world. Now Hagdaev wants to use this knowledge to help patients change this trend.
"What if we could teach the patient to divert attention from internal voice to the outside?" - Said Hagdaev.
The scientist decided to hold exeperimental: patients were given headphones that on the left and right ear were fed different syllables, for example on the left "pa" to the right "that." The subjects were not told that the sounds are different and asked to say what they heard.
Healthy people usually tell from the tone of the sound of the right ear, as the brain perceives sound signals better because of it. This is due to the fact that on the right ear signal falls faster than in the left temporal lobe, the place where sound information is processed.
What was surprising to scientists, when, when applying the same sound signals during hallucinations in patients with schizophrenia, the left temporal lobe of the brain is not "hyper-activated," as the researchers expected, but did not respond. Patients do not hear the sound in the right ear.
Thus Hagdaev stepped aside without suppressing drug hallucinations. Already developed an application for mobile phone through which people with schizophrenia can "train" the brain not to hear hallucinations.
