Which of the following scientific technique is a way to amplify a small electric current to make it easier to detect?

  1. EEG

  2. MRI

  3. Psychopharmacology

  4. Electrolysis

The correct answer is: EEG

EEG is the correct answer because it is a scientific technique used for testing the electrical activity of the brain. It amplifies small electric currents to measure brain activity and detect any abnormalities. The other choices are incorrect because they do not involve amplifying electric currents. MRI is a scanning technique that uses strong magnets and radio waves to produce detailed images of the inside of the body. Psychopharmacology is the study of how drugs affect the brain and behavior. Electrolysis is the process of using electricity to separate molecules into individual components.
