Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Sonal is at a brain research center, participating in a study. She is hooked up to a machine that measures electrical activity in her brain through the use of electrodes attached to her scalp. Which technique is the researcher using with Sonal?
A
EEG
B
MRI
C
fMRI
D
CT scan
Explanation: 

Detailed explanation-1: -Electroencephalography (EEG) is a non-invasive and relatively inexpensive method for assessing neurophysiological function that can be used to achieve this goal. EEG measures the electrical activity of large, synchronously firing, populations of neurons in the brain with electrodes placed on the scalp.

Detailed explanation-2: -In addition to examining the normal development and activity of the nervous system, neuroscience studies diseases, disorders, and injuries that affect parts of the nervous system, how it develops, and how well it functions.

Detailed explanation-3: -These technological methods include the encephalogram (EEG), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). These techniques ultimately have the same goal in that they aim to produce coherent representations of the brain.

Detailed explanation-4: -Functional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity. It may be used to examine which parts of the brain are handling critical functions, evaluate the effects of stroke or other disease, or to guide brain treatment.
