The fMRI employs a magnetic field to collect information about the body. It is one of the most prominent methods in neuroscience for studying the structure of the brain, including differences in the structural characteristics of different people's brains.
It works with a system that produces images of the brain's functions that indicates whether the activity of neurons is increased or decreased in specific parts of the brain and under which conditions.
The use of EEG allows further research on the following:
Moreover, the EEG has a mobile version "mobile EEG" that can study brain activities of real-world behaviors like kissing romantic partners.
Emission Computed Tomography is the most invasive method for brain imaging. Its name comes from the emission of radioactive energy by tracers injected into the blood - which is a signature aspect of this approach to understanding the brain.
The two major types of ECT are:
Each of these uses different types of radioactive isotopes and they are monitored in the brain using different tools.
To use the ECT method is to inject radioactive atoms into the person's bloodstream and have them circulated into the brain. The energy emitted is monitored by external devices that provide information about their concentration in the brain. Lastly, a mathematical model allows the data on radiation to be translated into information about brain processes.
This method allows researchers to analyze one's physiological process in ways other forms of brain imaging cannot, and more.
