Detection of stress and the effects of central nervous system depressants by gastrointestinal smooth muscle electromyography in wakeful rats

The smooth muscle EMG instrument can measure the level of acute stress and is applicable for the investigation of central nervous system affecting drugs through the GI tract in awake rats. This is the first tool to measure the stress response via the GI tract reactions. The technique may open a new perspective in the diagnosis and therapy of psychosomatic disorders.
