Scientists find way to Erase Memories
During the erase memories existed only in science fiction movies. However, scientists have found a way to eliminate the memory and restore it as easy as turning on the lights.
The discovery has been in trials on mice it is claimed will be the answer to all human anxiety. Those with phobias, army war trauma, to patients with dementia, can be cured.
how does it work? Similar objects used in the Will Smith movie Men In Black to erase the human short-term memory, memory fiddling this time also use a flash of light.
Researchers from the University of California found, stimulates nerves in the brain with optical lasers can erase the memory. In theory, because the brain makes memories formed neuronal relationship.
Weakened or strengthened connections - called synapses - can remove or form a memory. Research conducted on the nerves in the brain of mice that had been modified so that the light sensitive.
Researchers use optical lasers at specific frequencies, and at the same time giving an electric shock to the feet of mice. Soon, laser optical mice to associate stimuli with pain.
As a result, each given the same stimuli, mice showing expression of pain. Then the researchers do otherwise. Low-frequency optical laser was applied to remove the memory.
Again, the study successfully. Pain memory has been erased from the brains of mice. When fed a high-frequency blast again, memory back pain appears. Though no longer stimulated rat foot electric current.
"We formed a memory, erase, and re-enable it at will by applying a stimulus to strengthen or weaken synapses," said Roberto Malinow, professor of neuroscience.
According to him, a new breakthrough that could help people with Alzheimer's. Therefore, he found that Alzheimer's patients drugs weaken synapses in the same way as research.
While Thomas Insel, Director of the U.S. National Institute of Mental Health judging, the finding could explain how memory plays a role in the disappearance of emotional memories mental illnesses such as post-traumatic stress disorder.
