Kazan neurophysiologists suggested looking for ischaemia on encephalograms
The experiments were carried out on rats. They were forced to develop ischemia in various parts of the brain by introduction of endothelin — a substance that causes spasms of the arteries. After that, EEG were recorded using electrodes implanted in animals. The obtained records were then compared with electroencephalograms of the rats that did not have ischemia of nervous tissue. As it turned out, the electroencephalogram of animals with experimentally caused impairment of the blood circulation of the brain is different from that of healthy rats by a number of parameters. Differences manifest themselves just a short time after the development of ischemia.
If the results of the study prove to be applicable to people, physicians will have a method of quickly identifying foci of impaired blood circulation in the brain if a person has suffered a closed craniocerebral injury.
