For quite a long time, the cause and source of the itching remained a mystery. Some nerves filed a response to the stimulation of itching, but it did not give the opportunity to identify nerve fibers, which caused the desire to scratch.

In some time, scientists believed that the itching and pain "answer" the same nerves, only perceived by the brain they are different.
