A secure and reliable work, another opportunity to challenging, it is difficult to decide, distressing. Have you ever experienced this restless feeling? United States scientists recently reported the results of new research shows that this feeling could be controlled by the cerebral cortex.
According to the latest issue of United States Science magazine reported that previously had been found, a substance known as serotonin can calm emotions, inhibit anxiety. But the serotonin in the brain plays role in many places, including the cerebral cortex, Hippocampus (memory hub), amygdala (fear hub), and so on. In the end is which part of the brain specifically responsible for the anxiety, but also not very clear.
You can combine with serotonin receptor substances have a dozen or so, Columbia University scientists focus on one of these is called the 5HT2A receptor, the receptor key to play a role in the cerebral cortex. Their experimental rat "training", so that the mice have a sense of security and comfort, make your selections, for example, is to be in the dark or bright areas.
As a result, ordinary mice showed when faced with a choice, and genetically anxiety treatment, the body lacks the 5HT2A receptor in rat and less anxiety, but more choice to experience new things, such as in bright surroundings. If you recover this receptor in the brain function, in mice will become anxious.
Scientists accordingly considers that the anxiety may be cerebral cortex control, if enhanced relevant receptors in the brain, might help in the treatment of anxiety disorders.
