The International QEEG Certification exam has evolved over several years. We are now on the seventh edition. In the beginning, questions on artifacts were at the beginning of the exam in one section. The board felt that identifying artifacts would be a good way to start the exam as most people could do this without too much trouble.
We were wrong! Applicants not only had difficulty identifying artifacts, but many applicants also experienced anxiety which sometimes disrupted the rest of the test taking. Fortunately, this is no longer the case. Feedback to the mentors and didactic course providers helped to remedy the problem.
The ability to identify artifacts is crucial. Brain maps are averages of metrics like power and coherence. The average metrics can be misleading. For example, without inspection of the raw data, it would be difficult to discern the difference between muscle tension artifact and high spindling Beta. Increased Delta could be indicative of small movement artifact. Epics of diffuse high amplitude slowing might totally be missed. In other words, the results of the brain map must be interpreted in context of the raw data.
I would encourage people to become true “experts” in the examination of raw data by learning to identify artifacts, and, to learn to examine and interpret raw data with different montages to allow a better understanding of the resulting brain map.
