Solution

The correct answer is: "... it can show neurons' firing directly."

Here's why:

  1. Spatial Resolution: fMRI actually has better spatial resolution than EEG. fMRI can visualize brain activity at the millimeter level, while EEG's spatial resolution is more limited.

  2. Neurons' Firing: EEG measures electrical activity in the brain, which is a direct result of neurons firing. fMRI, on the other hand, measures changes in blood flow, which is an indirect measure of brain activity.

  3. Causality: Neither EEG nor fMRI can definitively answer questions about causality. They can show correlations between brain activity and behavior, but they can't prove that one causes the other.

  4. None of the options: As explained above, the statement about neurons' firing is correct, so this option is not correct.
