“Memory is the diary that we all carry with us,” Oscar Wilde once said. Now imagine for a second a life without any memories! One would not be able to remember one's name, how to take care of oneself, or even recognize one's own friends and family. It would be impossible to live happily without its memories. This is why our memories are essential points in our lives. These are the building blocks of our current self. For these reasons, it is very helpful to find as much information about this as possible. It is precisely for this purpose that this research paper was written. The goal of this research is to discover the truth about how the human brain stores and retrieves memories. Throughout this research, topics such as the definition of memory, types of memory, diseases causing memory difficulties, as well as the most well-known déjà vu phenomena that are caused by a certain type of memory process will be addressed. The word memory can be defined in several ways depending on the field in which the term memory is used. To begin with, the most commonly used definition of the term memory is the name given to the human ability to encode, store, retain and then recall past information and experiences in the brain. It is a sum of what we remember in total and it allows us to learn and adapt from previous experiences and form relationships.
