This study hopes to promote the use of wireless EEG technology on employees in high-risk fields, such as air traffic controlling, to monitor alpha wave activity and gauge the attention level of the employee.<ref>{{cite web|title=Brain Wave Patterns Can Predict Blunders, New Study Finds|url=http://www.news.ucdavis.edu/search/news_detail.lasso?id=9031|work=UC Davis News and Information|publisher=University of California, Davis campus|date=2

==Alpha waves in a gelatinous conductor==

As demonstrated by Adrian Upton, it is possible for extraneous sources to cause signals to appear on an EEG readout, causing false signals to be interpreted as healthy alpha waves while the patient's brain that is assumed to be still living is in fact, long dead. An excerpt from the article documenting this fact:
