Question

Evoked Potential Studies (EPS) enables us to
A) Evaluate different sensory functions
B) Detect clinically silent tensions
C) Study hearing and vision in children
D) All of the above

Answer 1

Hint: Evoked potential is nothing but the electric potential that are formed in different parts of the body nerves in response to the stimulus and this electric potential is carried to different parts of the brain for the response, and the power of the electric potential which is generating is less than millivolts and this is different from EEG.

Complete answer:
Evoked potential studies are conducted to study the electric signals that are generated to different senses of the body such as touch, vision, smell, etc.
This test is mainly conducted to know the sensory neurological problems and as a diagnostic test in some brain diseases.
It is also used to conduct in diagnosing some vision and hearing problems in children especially.
The electric signals which are generated here have very less range that are less than microvolts.
The test conducting by using the electrodes, it is painless procedure where the patient in which test should be done make to lie on bed and one electrode is attached to the scalp, and other is attached to the part where it is to be tested, and the stimulus is made, normal people get the electric signals instantaneously, if it is not happen, then any underlying disease might be there.

So, the correct option is D.

Note: Evoked potential studies are used to test the sensory functions of the people in and some children for vision and hearing, apart from this they are used to study brain activity in the coma patients and this test helpful to confirm the brain death in some cases.
