eeg-erp yikes

Today we learned about a brain scanning process called EEG-ERP (electroencephelogram-event related potentials). It provides high temporal resolution, but very low spatial resoltion. That means it allows the researcher to see fine details in brain reactions in terms of *when* they occur in response to a stimulus, but *not* very much detail about *where* in the brain the reaction is occuring. But the creepy thing is the "helmet" they put on the subject's head while they are doing the EEG-ERP. Yikes.
