The thesis of this paper is based on Dr. Larsen's book entitled: Perilous Rapture: On the Dangers of Fundamentalistic Thinking. Larsen takes the position that some kinds of myths are extremely dangerous, and polarize our duality-prone nervous systems still further, into dysfunctional and even pathological patterns. The thesis dates from an idea of Joseph Campbell's that our brains are the hardware, and culture the software, of human functioning. Taking into account both structural features, such as laterality in the hemispheres, and dynamic features such as EEG asymmetries, Larsen shows how we can utilize our neurobiology dysfunctionally or, on the contrary, optimally, depending upon the myths we hold, and how we conduct our habitual mental lives. Neurofeedback can provide us with an alternative to concrete and literalistic thinking. Optimal performance is achieved through flexibility and synchrony of the regions of the brain.
