Psychology I / Brain Imaging Techniques
Practice question · Sort into groups

Sort each technique or property by the kind of resolution it excels at.

Groups: Excellent TEMPORAL resolution (when) · Excellent SPATIAL resolution (where)

Hints
  1. Temporal resolution is about timing (when); spatial resolution is about location (where).
  2. EEG nails timing but not location; fMRI nails location but lags in timing.
Show the answer

Excellent TEMPORAL resolution (when): EEG, Tells you precisely WHEN neurons fire, to the millisecond

Excellent SPATIAL resolution (where): fMRI, Locates activity to within millimeters

Why

EEG has millisecond timing (temporal) but poor localization; fMRI localizes to millimeters (spatial) but lags in time. The core trade-off is knowing WHEN versus knowing WHERE.
