Electroencephalogram (EEG) measures the electrical activity of the brain! We record the brain activity by using the EEG while the participants complete computer tasks. 

 

This is a non-invasive procedure which involves placing a soft, stretchy EEG cap - like a swim cap - on participants’ head.  

​

The sensors on the EEG cap measure brain activity. These sensors are filled with a water-soluble gel to record the brain activity at the scalp more accurately. The gel is completely harmless and painless and easily washes off with water. Our lab has sinks and towels for participants to clean their heads afterward.  

​

The electrical signal recorded by the EEG cap is then amplified, transmitted, and stored in a password-protected computer for analysis.
