1. Huber, M., Siol, T., Herholz, K., Lenz, O., Köhle, K., & Heiss, W. D. (2001, December). Activation of thalamo-cortical systems in post-traumatic flashbacks: A positron emission tomography study. Traumatology, 7(4), 131-141. doi:10.1177/153476560100700402.

Abstract:
Trauma victims with post-traumatic stress disorder (PTSD) often experience ‘flashbacks’ that are described as being different from memories of other fearful biographic situations. We used Positron Emission Tomography and Statistical Parametric Mapping to compare in the same subject brain activation patterns during induced flashbacks with recall of fearful non-traumatic situations. During fearful recall there were significant activations of right precuneus. When traumatic memories were compared to neutral, right lingual gyrus, right thalamus / mamillary bodies, and right cerebellum were significantly activated. When brain activation during flashbacks was compared to simple fear, right mediodorsal thalamus (MD), right precuneus, and right cerebellum were significantly more active. With respect to recent experimental evidence concerning the function of thalamo-cortical systems, we hypothesize that post-traumatic flashback experiences are based on hyperactive thalamo-cortical ‘closed loop’ networks.

Language: English

Format: Journal

Abstract:
This discussion explores, briefly, the position that the repetitive redirecting of attention in EMDR is capable of turning on the brain's REM sleep system, leading to the activation of specific areas of the the anterior cortex of the cingulate gyrus, facilitating its function as a filter, thereby facilitating the integration of traumatic memory into general semantic networks. This integration is seen to lead to the subsequent reduction in both the strength of hippocampally mediated episodic memories of the traumatic event as well as the amygdaloid mediated negative affect of PTSD. The possibility is suggested that another underlying mechanisms of EMDR stimulation is the activation of the lateral cerebellum. The contribution of the cerebellum to cognitive and language functions is explored. The activation of the dentate nuclei in the lateral neocerebellum is shown to facilitate activation of the ventrolateral and central lateral thalamic nuclei. The activation of the ventrolateral nucleus is shown to lead to the activation of the left dorsolateral prefrontal cortex; further facilitating the integration of traumatic memory into general semantic and other neocortical networks.

Language: English

Format: Journal

Abstract:
A variety of nervous system components such as medulla, pons, midbrain, cerebellum, basal ganglia, parietal, frontal and occipital lobes have role in Eye Movement Desensitization and Reprocessing (EMDR) processes. The eye movement is done simultaneously for attracting client's attention to an external stimulus while concentrating on a certain internal subject. Eye movement guided by therapist is the most common attention stimulus. The role of eye movement has been documented previously in relation with cognitive processing mechanisms. A series of systemic experiments have shown that the eyes’ spontaneous movement is associated with emotional and cognitive changes and results in decreased excitement, flexibility in attention, memory processing, and enhanced semantic recalling. Eye movement also decreases the memory's image clarity and the accompanying excitement. By using EMDR, we can reach some parts of memory which were inaccessible before and also emotionally intolerable. Various researches emphasize on the effectiveness of EMDR in treating and curing phobias, pains, and dependent personality disorders. Consequently, due to the involvement of multiple neural system components, this palliative method of treatment can also help to rehabilitate the neuro-cognitive system.

8. Bergmann, U. (2008, September). The neurobiology of EMDR: Recent findings and insights. Presentation at the annual meeting of the EMDR International Association, Phoenix, AZ.

Language: English

Format: Conference

Abstract:
Given that EMDR originated as an empirically driven method, there has persisted a need for a more defined theoretical and neurobiological model of EMDR’s reported robust effects. This presentation will synthesize the existing research on memory formation. Specific attention will be given to recent empirical findings, involving the thalamus in somatosensory integration and in episodic and procedural memory integration. This material will be integrated with previously posited theories regarding the cerebellum’s involvement in many aspects of information processing and activation processes of the frontal lobes and EMDR’s activation of the neurophysiology of REM-sleep systems.

10. Bergmann, U. (2006, September). The neurobiology of EMDR: Thalamic, cerebellar and pontine/REM processes. Presentation at the annual meeting of the EMDR International Association, Philadelphia, PA.

Language: English

Format: Conference

Abstract:
Clinical case reports and a growing body of controlled research suggest that EMDR is equally and perhaps more efficacious when cross-compared with other methods in treating Posttraumatic Stress Disorder. However, as EMDR was originally an empirically driven method, there has persisted a need for a more defined theoretical model, further scientific validation, and a neurobiological understanding of EMDR's reported robust effects. The possibility that EMDR can effectuate change on a neurobiological level has fueled speculation as to the neural-mechanisms that might underlie EMDR's effects. Brain scans and QEEG's are beginning to shed light on the alterations of brain function that EMDR appears to yield. This presentation will synthesize the existing research with theoretical speculation correlated with Francine Shapiro's model of the Adaptive Information Processing System. Specific attention will be given to recent empirical findings involving the thalamus in information processing and memory integration. This material will be integrated with previously posited theories regarding the cerebellum's involvement in many aspects of information processing and activation processes of the left prefrontal areas and EMDR's activation of the neurophysiology of REM-sleep systems. A neurobiological definition of EMDR serve to further legitimize its usage. It can also potentially enlighten our practice by informing preparation, resourcing and target selection strategies.
