Erasing specific memories is possible




Researchers of a medical college have a drug that could be developed in order to remove it. Memories selectively used In mice, the scientists were successful with the drugs.

MRI-scan hersenen Scientists at the Georgia College of Medicine developed the chemicals specifically for mice brains, but the protein that causes memory loss, also occurs in people. The researchers gave the mice in a locked room hear a sound, followed by an electric shock. In the control mice a Pavlovian response allowed the mice are afraid when they hear the sound. The mice that received the protein in memory at the time the sound was played back were administered, lose their memory. The researchers demonstrated this by putting the mice exposed to the sound: the mice with an erased memory were not panicking.

The corresponding protein in which the mice were given an overdose of, alpha-CaMKII, is also used by the human brains. According to Dr. Joe Tsien method that works his group is not used on humans. The operating principle might, however, be applicable. On the human brain The researchers found that the alpha-CaMKII protein plays an important role in the development of memory. However, when the protein is available in large quantities for the brains, the reminder that approached during the overdose will be deleted. A pill could look after them. Overdose That way unpleasant memories would like traumatic events aimed erased can be.
