The following considerations are from the SoniModul site. Originally they are only in French. I thought it might be of interest for number of members here as much as it was for me.
The psycho-emotional dimension
The concept of thalamocortical dysrhythmia (DTP) allows (and the clinical context requires) a thorough integration of the psycho-emotional (or ideo-affective) dimension into the therapeutic process. The activation and optimization of self-healing mechanisms are directly related to this.
There are strong indications that there are two sources underlying the DTP process: first, a physical or cerebral abnormality (e. g. amputation) and second, intense and persistent mental activities, i. e. ideas and representations and their associated feelings, which can be activated by the presence of a state of chronic illness and suffering, but also by personal biographical factors and personality/character traits.
Our experience clearly indicates that surgery makes it possible to control DTP related to disease and emotions while indirectly and logically providing mental improvement and an increase in quality of life due to the reduction of symptoms thus obtained. However, these therapeutic effects cannot take place if a counter-productive mental dynamic contributes to suffering and has not yet been managed and resolved by appropriate psychotherapeutic measures. This is most likely due to the wide and bilateral distribution of the paralimbic/associative thalamocortical network responsible for mental functions (which we will briefly call the "emotional brain"), as well as its wide interconnectivity with other sensory and motor sectors. This gives the emotional brain a strong and potentially dominant force, in other words, the patient's mind is stronger than the intervention and the surgeon, and this is undoubtedly an essential observation that fully supports our integrative therapeutic approach. This discussion also provides an important observation, often overlooked in our materialistic and linear medical cultural context, that a human being can suffer from intense neurological symptoms from two sources, one somatic and the other mental, clearly illustrating the need for integration of these two therapeutic dimensions.
Recent experimental evidence indicates that mental activity, particularly emotional activity, can lead to not only DTP in the brain, but also cellular loss through different mechanisms, which has been impressively demonstrated for several years in various ethnological studies, proving that a deep conviction can lead to physical damage or even death. Hence our great responsibility for our brains: our ideas, representations and beliefs can activate processes of cellular loss, but we can also trigger and promote beliefs and emotions that lead to brain health, well-being and the activation of our self-healing possibilities, which are greatly underestimated.
