How do EEGs work?
Your brain cells (neurons) communicate with each other using electrical signals. This activity creates small electrical impulses. During an EEG, small sensors called electrodes are placed on your scalp. These electrodes pick up the electrical signals produced by your brain. The electrodes send the signals to a computer, which records them. This creates a visual representation of the brain's activity, often shown as waves on a screen or paper. Researchers look at these waves to understand how your brain is functioning. They can analyze how your brain responds to certain stimuli after performing tasks.
EEG Studies at CUTA
We utilize EEG (electroencephalography) in many of our studies. EEGs measure electrical activity in the brain by placing small sensors on the scalp. The EEG data collected in our lab offers insight into the neural mechanisms behind emotional regulation, anxiety disorders, and OCD. We are currently conducting two EEG studies - Neurofeedback and OCD Interp. If you are an SDSU undergraduate interested in being a research participant, please sign up on SONA.
