Scientists serotonin affects depression

A new study at Wayne State University are questioning what a serotonin deficiency plays a Central role in depression.

In experiments on mice, scientists have found that rodents lacking the ability to produce this chemical compound in his brain, did not show signs of depression. Group under the management of Donald Kuhn "created" mice that lacked the ability to produce serotonin and conducted a series of tests.

Laboratory mice were compulsive and extremely aggressive, but he showed no signs of depression. In addition, the experimental group of rodents under stress behaved in the same way as a normal mouse. And when the "changed" command, the animals were treated with antidepressants, they showed a reaction, like ordinary rodents. Scientists have concluded that the data suggest: serotonin is a key factor in depression and need to look for other causes.
