What follows is a project-in-process. It is being done to assist the staff at our centers in their work using EEG Biofeedback (neurofeedback). It is to be a part of The Companion to The Neurofeedback Book which is being written at this time. If it can be a helpful starting point for others, then they are welcome to use it. Each BA has many different functions associated with it. We have attempted to list one or two commonly mentioned functions for each site with no attempt to mention them all. To be inclusive would have defeated the purpose of this summary, which was to give our staff rudimentary information relating Brodmann Areas to different 10-20 sites.
Functions for each Brodmann area are outlined below. This preliminary document represents a best guess based on our clinical observations and on the work published (or unpublished) by others. We must start somewhere, however, the detail of functions for each Brodmann area is necessarily FALSE. Why? Because all functions are a result of the interaction of many areas. As Dan Lloyd of Trinity College, Hartford, CT, so succinctly put it, “The typical BA is differentially engaged in 40% of behavioral (cognitive, perceptual, emotive) domains” (Lloyd, 2007). This is one reason why coherence and phase training may become increasingly important in EEG Biofeedback.
NOTE: Please do not get confused. A Brodmann area does not (necessarily) correspond precisely to a named gyrus on the cortex. In the following we have tried to give as close a correspondence as possible. We have given the closest approximation of 10-20 sites to the Brodmann areas as we could. Please e-mail to us your suggestions for corrections; they are appreciated. firstname.lastname@example.org
Dr. Thompson, ADD Centre & The Biofeedback Institute, Canada; Dr. Wu Wenqing, Friendship Hospital & Capital Medical University of Beijing and Dr. James Thompson AANI, New York, USA have made this attempt to simplify and put in summary form the work of many others. Special thanks are extended to Mark Dubin, Dan Lloyd, Richard Soutar, Bob Thatcher, Johnathan Walker, and many others who have given us their summaries or whose work is available on the internet. These persons are mentioned because they were consulted or used as primary references. All have spent considerable time compiling data on this subject.
Note: A dash between sites, (F3-C3) means ‘between these two sites’. The following short forms are also used: Mirror Neuron System(MNS); left hand side(LHS), right hand side(RHS), Brodmann Area(BA); and (?) means we don’t have a reference. Figures are adapted from The Neurofeedback Book. (Original illustrations by Amanda Reeves with colouring and numbering of areas by Bojana Knezevic)
