,### 1. Which neuroimaging technique uses radioactive
tracers to measure brain activity?
- A) MRI
- B) fMRI
- C) PET
- D) EEG
Answer: C) PET
- Rationale : Positron Emission Tomography (PET) uses
radioactive tracers to visualize brain activity by measuring
cerebral blood flow and metabolic rates.
### 2. What is the main advantage of using functional MRI
(fMRI) over EEG in studying brain activity?
- A) Temporal resolution
- B) Spatial resolution
- C) Simplicity of data interpretation
- D) Cost-effectiveness
Answer: B) Spatial resolution
- Rationale : fMRI provides greater spatial resolution
compared to EEG, allowing more precise localization of
brain activity.
### 3. Which method is most suitable for studying the
functional connectivity between brain regions?
- A) DTI
- B) MEG
- C) TMS
- D) Optogenetics
, - Rationale : Diffusion Tensor Imaging (DTI) is used to
map and characterize structural connectivity by modeling
the diffusion of water molecules along white matter tracts.
### 4. Which technique is best suited for manipulating
neural activity with high temporal precision?
- A) fMRI
- B) TMS
- C) PET
- D) NIRS
Answer: B) TMS
- Rationale : Transcranial Magnetic Stimulation (TMS) is a
non-invasive method to stimulate small regions of the brain
with high temporal precision.
### 5. Which of the following research methods directly
measures neuronal electrical activity?
- A) fMRI
- B) PET
- C) EEG
- D) DTI
Answer: C) EEG
- Rationale : Electroencephalography (EEG) records
electrical activity generated by neurons, providing direct
measurement of neuronal activity.
