plz give information on erasing and implanting human memory but dont copy from net answer me from any book
Answers
Evolution of human beings allows people to forget things because the quality of life rests with the selective erasure of memory. Recent research suggests that fear memories can be near instantly erased and that specific proteins have significant powers to abolish them. This happens through production of a protein called alpha-CaM kinase II. Scientists have found that this protein can be used for selective deletion of fear memories in mice.
The term “engram” is used to describe where memory is stored. There are many engrams in different regions of the brain, each used for a different purpose. For instance, the amygdala is responsible for fear memories and the interpositus nucleus is responsible for conditioned stimulus.
Brain with many engrams
Through experiments in mice, researchers discovered that neurons associated with memory can be boosted with a protein called CREB, and memories can be erased with a protein called alpha-CaM kinase II. Also, those neurons can be activated to form false memory.
Remembering
For short term memories, a protein called Kinase A is produced. However, sometimes, Kinase A is produced in such abundance that it causes MAPK, another protein, to be produced. MAPK causes a protein called CREB to be produced. CREB is essential for forming long-term memories.

False Memory
People are found to have false memory too. For example, in many court cases, defendants were found guilty based on testimony from witnesses who were sure of their recollections, but DNA evidence proved otherwise. Researchers in MIT found that by reactivating neurons associated with a particular memory, false memory could be planted into the brains of mice.
