In order to help people suffering from many years of heavy flows of epilepsy, it is necessary to conduct a diagnostic study of the brain. But do it without surgery is not easy. A scientist from the University of Arizona, offers his own method.
In the case of such disease patients require surgery to remove a section of tissue. To do this, set the exact position of the region of the brain, the source of a convulsive seizure.
Electroencephalography is not a good helper, because it provides a low resolution image, and the introduction of the electrodes, allowing up much more accurate maps of the brain, is always a risk of infection (and sometimes there are strange hallucinations ).
The effect is as follows: the phase and magnitude of the voltage passing through the skin, proportional to the pressure of ultrasound directed at a particular body part.
In practice, this means focusing on a small section of skull ultrasonic beam changes its physical properties. The result is a kind of "electric box" that allows you to look inward, to accurately measure the weak electric field, which normally do not go beyond the human skull.
And so there they can be caught using standard equipment such as EEG (electrodes placed on the head as a hat). Further built more accurate maps can be used to determine exactly what area you want to delete.
