The article for psychology Many different technologies for brain researching are developing in our days, because the brain is discovered too much today. Such equipment like fMRI and PET have given to researches an opportunity to learn more about structure and functions of the human brain. With help of new technologies scientists can find out differences between brains of two genders, can discover the structure of brain in details. Such way of researching is used in psychology, medicine and even in special scientific labs. Now we should learn more about every kind of new equipment. The first one is the PET scan. This type of scanning lets us to see detailed 2- or 3-dimensional color pictures. So, we can observe exactly which part of brain is active while the person is doing something. Of course it is a big benefit of this kind of technic. But the disadvantage is that person has to be injected with radioactive substance before the researching. Therefore many people consider that such way of discovering is very dangerous for their blood and, as consequence, for health of their head. The second type of scanning is fMRI. This technic is able to sense oxygen in the human brain. The blood with this gas concentrates in the most active areas of the brain. fMRI uses the magnetic field to explore and compare the amount of oxygen in our brain. Such technology has more advantages, because it doesn’t seem so dangerous for health and researchers can get color motion images as result. To summarize we can say that new technologies such as PET and fMRI give researchers and scientists a possibility to learn about the human brain more detailed information. Especially contemporary scientists have already found out peculiarities of males and females brains. But it is only the first step of using new technologies of scanning and, probably, soon PET and fMRI will help us to develop knowledge about brain.
