“Unwanted Memories is Erasable” Says Scientist

Dear friends we want memory but not all the memory. We like those memories which give happiness or a good feeling. There are memories stored in our brain, which we don’t like to recall because they don’t give a sense of happiness, or good feeling, such unwanted memory is difficult to erase. In psychology, memory is an organism's mental ability to store, retain and recall information. But you must be happy because the following studies show that the unwanted memories might be erasable.

• Spotless Mind? Unwanted Memories Might Be Erasable Without Harming Other Brain Functions: A molecule known to preserve memories -- PKMzeta -- specifically stores complex, high-quality memories that provide detailed information about an animal's location, fears and actions, but does not control the ability to process or express this information. This finding suggests that PKMzeta erasure that is designed to target specific debilitating memories could be effective against the offending memory while sparing the computational function of brain.[1]
• Process For Storing And Erasing Long-term Memories Discovered: Are memories recorded in a stable physical change, like writing permanently on a clay tablet? Scientists recently discovered that the process of storing long-term memories might involve a miniature molecular machine that must run constantly to keep memories going. When they "jammed" this machine -- a protein -- in mouse brains, they succeeded in erasing specific memories.[2]
• Scientists Discover Memory Molecule: Scientists have succeeded in erasing memory in animal models. These findings may be useful for the treatment of disorders characterized by the pathological over-strengthening of synaptic connections, such as neuropathic pain, phantom limb syndrome, dystonia and post-traumatic stress.[3]
• Scientists Show Hippocampus's Role In Long Term Memory: The formation of new memories and the retrieval of older memories are both evidenced in the hippocampus region of the brain, according to recent research by NYU neuroscientists.[4]
• Scientists Uncover How Brain Retrieves And Stores Older Memories: Scientists at The Hospital for Sick Children (Sick Kids) and UCLA have pinpointed for the first time a region of the brain responsible for storing and retrieving distant memories.[5]
