Scientists have discovered that the hippocampus inside the gray matter of the brain can function as a memory storage box, but the resolution of this storage area city is not strong, and the stimulation of the same brain area city can cause it to produce real and false memories. Memory is separated from false memory, and researchers have proposed a method to strengthen memory through background recall. If something has not really happened, it is difficult to strengthen the human brain's memory of it through this method. This text is mainly about:.
