Changes of autonomic nervous system indices and cerebral blood flow during EMDR standard protocol

Description

We have reported that cerebral blood flow in Orbito Frontal Cortex increased, and blood flow in the Transverse temporal gyrus decreased with desensitization(Ichii et al, 2012). We collected the data of cerebral blood flow and other physical indices during EMDR. Purpose of this study is to inspect the physiological change by EMDR.

In this study, we treated traumatic memories of six right-handed healthy adult males and females using EMDR standard protocol while measuring the NIRS(Near Infrared Stereoscopy). And we collected data of autonomic nervous system (skin conductance, finger plethysmogram) for the four of them simultaneously.
The data of NIRS duplicated our previous study, that is sharp increase with starting eye movements and quick decrease after stopping eye movements. And also, finger plethysmogram decreased with starting eye movements and it showed gradual decrease from the beginning to completion of intervention. EMDR might be able to suppress the excessive activation of reward system. And there is a possibility that eye movements can activate the parasympathetic nerves.
