One of the leading researchers at Moscow State University’s Institute for Advanced Brain Research told socialbites.ca that five to ten large-scale brain networks are associated with the manifestation of hallucinations and delusions in schizophrenics. MV Lomonosov, Senior Researcher, Scientific and Clinical Research Center for Neuropsychiatry, Hospital. Alekseeva Vadim Ushakov.
“These structures are scattered all over the brain. Moreover, there are areas of common faults as well as those that do not belong to general faults. In the first approach, as they say, we calculated with a warm hand which regions worked where and saw the interconnected morphometric, tractographic and functional neural network changes. Now we will understand this in detail, ”explained Ushakov.
The researchers reached these results using MRI and polygraph. The polygraph reflects traces of memory that is important to a person. Using an MRI compatible polygraph, physicians can record upper and lower respiration, photoplethysmogram (volume of blood in veins), heart rate, cardiogram data using other devices, galvanic skin response.
“First of all, we present the patient’s own name. We know that a healthy person has a strong reaction to his name. And we look at the polygraph, what changes in indicators reflect the importance of the alert. Next, we need to use functional MRI (fMRI) to visualize the brain’s neural networks associated with delusions and hallucinations,” said Ushakov.
Specialists also present the patient with his own delusional plan, which is perceived as reality for the patient.
“Let’s say we presented: “The KGB is following me.” And the next time: “The doctors are watching me.” If according to his plan it is the KGB and not the doctor, then using the polygraph we will see the contrast between these two sentences and using the fMRI method we visualize the brain structures that are activated at the same time. ” He finished Ushakov.
Schizophrenia remains one of humanity’s most mysterious diseases. So far, the causes of its development have not been found, there is no objective diagnosis, it is completely incurable. Will there be a test for schizophrenia and what will it look like? report Ushakov “Newspaper.Ru”.
ancient scientists established The effect of paranoia on memory.
