Deck 7: Extension: B - Imaging the Brains Activity

Question 1

What distinguishes the ERP technique from standard EEG techniques?

Answer 1

EEG techniques are real-time, rhythmical, graded potentials from cortical neurons. ERP technique is the average of EEG segments that each follow a specific stimulus event.
