Neuroimaging has been shown to be a powerful tool to investigate EMDR neurobiological correlates demonstrating a clear association between normalization of brain functional changes and symptoms regression. In the recent past, a series of EEG…

In anxiety disorders, such as PTSD, brain imaging has demonstrated local modifications of functional activities using various techniques. In the present study the direct neuronal activities were measured in delta, theta and beta frequencies, using…

Eye movement desensitization and reprocessing (EMDR) has emerged as a promising new treatment for trauma and other anxiety-based disorders. However, the neurobiological mechanism of EMDR has not been well understood. This study reports changes in the…

The use of bilateral eye movements (EMs) is an important component of Eye Movement Desensitization and Reprocessing (EMDR) therapy for PTSD. The neural mechanisms underlying EMDR remain unclear. However, prior behavioral work looking at the effects…

Participants will be able to: 1) decribe phantom limb pain and its parameters; 2) understand the current use of MEG technology with respect to phantom limb pain; and 3) understand and describe EMDR treatment protocol for phantom limb pain.

10 patients suffering from PTSD following a severe traumatic event, were assessed with event-related brain potentials (ERPs) in a modified oddball paradigm containing auditory standard, target, and novel tones. ERPs were assessed before and after a…

The efficacy of a controversial treatment for posttraumatic stress disorder has been boosted for new evidence from brain imaging studies.

A growing number of functional neuroimaging studies on PTSD have described the abnormal response of amygdala and prefrontal cortex to traumatic stimuli. Abnormal activation of some parts of the prefrontal cortex might possibly be involved in the…

Over the last decade, EMDR(Eye Movement Desensitization and Reprocessing) has emerged as a promising new treatment for trauma and other anxiety-based disorders. However, neurobiological mechanism of EMDR has not been well understood. Authors report…

We studied the neural basis of reexperiencing in patients with PTSD using positron emission tomography (PET) and investigated the change in the neural activities from before to after improvement of PTSD symptoms. As a therapy for PTSD, we used the…

Several authors have found smaller hippocampal volumes in patients with PTSD and some have suggested that psychotropic drugs may promote hippocampus neurogenesis and reverse the decrease in hippocampus volume.1 However, the only study that has…

Psychotherapy is often effective for treating psychogenic disorders, but the changes that occur in the brain during such treatments remain unknown. To investigate this, we monitored cerebral activity throughout an entire session using a…

The study of traumatic memories is still an emerging field, both methodologically and theoretically. Previous questionnaire and interview methods for studying traumatic memories have been limited in their ability to evoke and assess remembrances with…

Whereas most patients with PTSD construct a narrative of their trauma over time, it is a characteristic of PTSD that sensory elements of the trauma itself continue to intrude as flashbacks and nightmares, altered states of consciousness in which the…

To better understand the pathophysiology and treatment of Posttraumatic Stress Disorder (PTSD), standard psychological testing, Rorschach Ink Blot testing, and neuroimaging using Single Photon Emission Computed Tomography (SPECT) were administered to…
