(Week 4 Update) Neurofeedback Databases: Neurorep

While I have still been setting up patients and training them myself, this week has been dedicated to creating QEEG reports. I was taught how to run a patient's test file, containing the raw EEG without any analysis, through a database. I was exposed to only the Neurorep database, but the ADD Clinic uses a total of four databases for each patients data. Below are the various databases. I have presented them in the following format. Name: Name of...

Database References

Since I will include many examples of qEEG reports in my next post, here is a brief guide to interpreting them. This is a very simplified version, and I will upload the more detailed one in the future. But before even attempting to understand the report, we must discuss common statistic terminology. Database: Organized collection of data (in this case, brain maps) Z-score Tables: Tables of data which indicates how many standard deviations an...

The Brodmann Areas

Created by German anatomist Korbinian Brodmann, the Brodmann Areas separate the brain into regions with similar cytoarchitecture (layering of neural tissue). Previously a psychiatric physician, Brodmann was introduced to the field of theoretical neuroscience research by Alois Alzheimer, who first identified Alzheimer's disease. Brodmann worked with the University of Berlin's Neurological Library to write his 1909 thesis on regions of different neural...

The 10/20 System

The 10/20 Locations As I mentioned before, in neurofeedback, electrodes are placed on the scalp according to the internationally recognized 10/20 system. The name stems from the fact that all electrode placements are either 10% or 20% of the entire across-head distance away from each other. The placements of each electrode are chosen based on the underlying portion of cerebral cortex (the outer covering of the brain.) Below is a diagram of the...
