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.

Abstract:
El trastorno por estrés postraumático (TEPT) se caracteriza por temor, desesperanza u horror intensos en personas que han sido expuestas a acontecimientos traumáticos. La terapia de Desensibilización y Reprocesamiento por Movimiento Ocular (EMDR), es reconocida como un tratamiento efectivo y eficiente para tratar el TEPT. Diversos estudios han demostrado alteraciones anatómico-fisiológicas y neurobiológicas en los pacientes que presentan este trastorno, ya que intervienen estructuras como la amígdala, tálamo y diferentes áreas de la corteza prefrontal. Debido a lo anterior, se han realizado estudios sobre los mecanismos neurales y la implicación neurobiológica de la terapia EMDR en el TEPT, así como alteraciones en la función cognitiva dentro de la sintomatología clínica que se observa en los pacientes con este trastorno.
Posttraumatic stress disorder (PTSD) is characterized by fear, helplessness or horror severe in people who have been exposed to traumatic events. Eye Movement Desensitization and Reprocessing (EMDR) is recognized as an effective and efficient in treating PTSD. Several studies have shown anatomical and physiological alterations in neurobiological patients with this disorder, and involved structures like the amygdala, thalamus and different areas of the prefrontal cortex. Because of this, there have been studies on the neural mechanisms and neurobiological implications of EMDR in PTSD, as well as alterations in cognitive function within the clinical symptoms observed in patients with this disorder.

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.

Abstract:
Recent neuroimaging studies on posttraumatic stress disorder (PTSD) have revealed a consistent decrease
in thalamic activity, relative to non-PTSD controls. Empirical studies of the past decade have
shown the thalamus to be centrally involved in the integration of perceptual, somatosensory, memorial,
and cognitive processes (thalamo-cortical-temporal binding). A theoretical model is proposed to suggest
that one underlying mechanism of EMDR stimulation (dual-attention stimulation/bilateral stimulation
[DAS/BLS] ) is thalamic activation, specifi cally of the ventrolateral and central-lateral nuclei. It is hypothesized
that this may facilitate the repair and integration of somatosensory, memorial, cognitive, frontal
lobe and synchronized hemispheric functions that are disrupted in PTSD.

Language: English
Format: Conference
Abstract:
Prior presentations focused on EMDR’s ability to activate REM-sleep systems and to mediate frontal lobe
activation. New research on the Thalamus and thalamo-cortical-temporal-binding and Somato-sensory
integration will be introduced. Accordingly, new speculations will be offered regarding EMDR’s ability to
reset/repair the impairment in thalamic functioning that is inherent in PTSD. This presentation will, also,
introduce more recent research, contrasting thalamic impairment in Type 1 PTSD vs. Complex PTSD. In addition,
new findings regarding the formation, content and storage of memory and its impairment, in PTSD, will be
explored vis-à-vis EMDR's ability to make repairs, in this area.

Abstract:
Clinical case reports and controlled research suggest that EMDR is equally and perhaps more efficacious than other methods in treating PTSD. However, as 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.

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.

Abstract: Given that EMDR originated as an empirically driven method, there has been a persistent need for a more defined theoretical and neurobiological model of EMDR's reported robust effects. This presentation will synthesize the existing research on information processing, as well as memorial, perceptual, cognitive and somatosensorial integration. Specific attention will be given to recent empirical findings, involving the hippocampus and thalamus in information processing and integration. EMDR’s DAS/BLS will be shown to activate REM-systems, as well as areas of the thalamus and frontal lobes, reduced in activation by PTSD, thereby allowing for the repair of perceptual, cognitive, memorial, somatosensory and inter-hemispheric functioning.

Abstract:
This presentation will synthesize the existing neurobiological research on information- processing. Specific attention will be given to recent empirical findings, involving the hippocampus and thalamus in perceptual, memorial, emotional, cognitive, and somatosensory integration. This data will be reviewed in reference to the organizing constructs of the Parallel Distributed Processing/Connectionism and the Thalamo-Cortical-Temporal-Binding models of information processing. Given that EMDR's application has historically been guided by information processing theory, this presentation will illustrate the neurobiological underpinnings of this foundation.

Language: English
Format: Conference
Abstract:
A neurobiological model of PTSD as a neuropsychiavlc disorder that can
be characterized by thalamocortical dysrhythmia is proposed. It is argued that PTSD is related to disruptions in thalamus-medicated temporal
cognitive binding. The resulting lack of corticothalamic dialogue may account for flashback experiences and primary dissociation, and the resulting inability to integrate the totality of what is happening into personal memory and identity. The presentation will discuss recent neuroscience research with regard to the effects of traumatic stress on brain functioning that is integrated with Shapiro's Adaptive Information Processing Model.

Abstract:
Some of the key players of the central nervous system in pain are the thalamus, the amygdala, the anterior cingulate cortex and the frontal cortex. The Central Nervous System is also not 'hard-wired' but kept in a stable state by elaborate control mechanisms. If these control mechanisms become unstable, as a result of say prolonged stress, neurological changes can occur, producing symptoms such as those found in trauma and chronic pain.
