When anxiety won't go away
Date:7/6/2012

whose gene for the formation of this substance had been disabled. After being exposed to a brief and unpleasant electric shock, the animals exhibited persistent anxiety symptoms, even if they hadn't been confronted with the negative stimulus over a longer time. Mice exhibiting a normal amount of released dynorphin were anxious to begin with as well, but the symptoms quickly subsided. "This behavior is the same in humans: If you burn your hand on the stove once, you don't forget the incident that quickly," explains Prof. Zimmer. "Learning vocabulary, on the other hand, typically tends to be more tedious because it's not tied to emotions."

Results are transferrable to people

Next the researchers showed that these results can be transferred to people. "We took advantage of the fact that people exhibit natural variations of the dynorphin gene that lead to different levels of this substance being released in the brain," reports Prof. Dr. Dr. Henrik Walter, Director of the Research Area Mind and Brain at the Psychiatric University Clinic at the Charit in Berlin, who also used to perform research in this area at the University Clinic in Bonn. A total of 33 healthy probands were divided into two groups: One with the genetically stronger dynorphin release and the other which exhibits less gene activity.

Unpleasant stimulus leads to stress reactions in the probands

Equipped with computer glasses the probands observed blue and green squares which appeared and then disappeared again in a magnetic resonance tomograph (MRT). When the green square was visible the scientists repeatedly gave probands an unpleasant stimulus on the hand using a laser. Scientists were able to prove that these negative stimuli actually led to a stress reaction given the increased sweat on the skin. At the same time, researchers recorded the activities of various brain areas with the tomograph. After this conditioning stage came part two of the experim
