There is no such imaging technique available for brain scan.
Magnetoencephalography (MEG) is a method used to calculate brain's magnetic field shifts due to external sensations, such as bodily touches or meal photos. The electric activity (current) in the brain induced such a shift in the environment.
Positron-emission tomography is a practical technique in nuclear medicine that is used to monitor body metabolism to help diagnose disease. A brain positron emission tomography (PET) scan is an imaging procedure that helps doctors in seeing how the brain works. The mri shows photos of brain function after nuclear tracers were ingested into the bloodstream. Such tracers are "linked" to the glucose compounds.
Blood-related changes are observed by functional MRI to test brain activity. The assumption that blood flows and neuronal activity are intertwined is the basis of this technique. Blood flow towards this area also tends to increase whenever a region of the brain is used.
In a communication model, the context is the environment surrounding communication, including the physical environment as well as the interpretation of a situation.
<u>Explanation:
</u>
A communication model is dynamic and exhibits changes based on its utility or the purpose of use.
Though there are changes in the use of these models, the context of the communication models usually remains the same even if the methodology changes.
The context of the model helps in carrying out the correct interpretation of the situation.
