Question

Given the following statements, which one of the options is correct?
Statement (i): Structural Magnetic Resonance Imaging (sMRI) has better spatial resolution than Electroencephalogram (EEG)
Statement (ii): EEG has better temporal resolution than sMRI

• A. Both the statements are correct
• B. Both the statements are incorrect
• C. Statement (i) is correct; statement (ii) is incorrect
• D. Statement (i) is incorrect; statement (ii) is correct

Hint:

For neuroimaging techniques: - sMRI is excellent for spatial resolution but lacks temporal sensitivity. - EEG provides exceptional temporal resolution but poor spatial detail.

Answer 1

The Correct Option is A

Step 1: Understanding the difference between spatial and temporal resolution.

• Spatial resolution refers to the ability to distinguish small details in an image or signal. It is typically higher in imaging techniques that capture detailed anatomical structures, such as Structural Magnetic Resonance Imaging (sMRI).
• Temporal resolution refers to the ability to track rapid changes over time. Techniques like Electroencephalography (EEG) offer excellent temporal resolution because they monitor fast neural activity.

Step 2: Analyzing Statement (i):
sMRI provides high spatial resolution, making it suitable for detailed visualization of brain anatomy, such as gray matter, white matter, and ventricles. This makes it an essential tool in structural brain imaging for clinical and research applications.

Step 3: Analyzing Statement (ii):
EEG has excellent temporal resolution because it captures electrical signals from the brain in real-time. This allows researchers and clinicians to monitor neural events as they happen, often on the millisecond scale.

Conclusion:
Since both statements accurately describe the characteristics of the respective techniques:

Correct Answer: (A) — Both (i) and (ii) are true.
