Advantages
- cheaper
- portable (smaller)
- safe
- natural settings (e.g. real human interactions instead of computer presentation)
- high temporal resolution (10Hz)
- less sensitive to head motion
- clinically friendly
- less environment noise
- long time recording
- can used on infants, children, or patients
- hyper
Disadvantages
- low spatial resolution (3cm)
- can only record brain surface
- no standard analyzing package
- inaccurate activation localization (or registration)
EEG has the following disadvantages over NIRS (Sitaram et al., 2007):
- long-term application and fixation of electrodes are difficult,
- portable devices are artifact prone,
- has low spatial resolution.
