Question

Mariah is a neuroscience graduate student interested in understanding how the human brain processes early childhood memories. What technique should Mariah use to determine which brain regions are activated when someone recalls his or her first memory?
A) Single cell recording

B)Positron Emission tomography

C) Evoked Potential

D)Transcranial Magnetic Stimulation

Answer 1

Answer:

Option-(B):Positron Emission tomography(PET).

Explanation:

• Positron Emission tomography(PET):

It is the advanced technique in order to make easy for the professionals to understand the metabolic activity of the living organisms. As the cellular structures have different metabolic activities or levels of reactions in which they produce the optimum level of products in order to drive the different body functions. As the positron emission tomography involves the analyses of the cells metabolic activities in the tissues or organ under-consideration of the professional. As the professional may face the need to know more about a certain disorder faced by the subject, along with the basic tests which are carried out, the organ or tissue is subjected to a very advanced form of nuclear medicine technology along with the use of biochemical medicines or chemicals to know the level of the metabolic activities inside the living being body. As it will clearly make it easy for the professional to know more about the disorder faced by the patient or the subject.

• The Mechanism:

The subject is placed on the specific panel and as the subject's body is targeted by the "gamma rays". As, the gamma rays reflection is captured by the machine and a clear image of the different chemical or metabolic activities are there for the professionals to know more about the subject's medical situation and diagnose the disorders (if any) faced by the patient.
