“Memory is the diary that we all carry with us,” Oscar Wilde once said. Now for a second imagine a life without memories! You would not be able to remember your name, how to take care of yourself or even recognize your friends and family. It would be impossible to live happily without your memories. This is why our memories are such vital points in our lives. They are the building blocks of our current self. For these reasons it is very useful to find as much information as possible about it. This research paper was written for this very purpose. The aim of this research is to discover the truth about how the human brain stores and retrieves memories. In the course of this research, topics such as the definition of memory, types of memory, diseases that cause memory difficulties, as well as the most well-known phenomena of déjàvu that are caused by a certain type of memory process will be discussed.

To begin with the most commonly used definition, in fact, the term memory is the name given to the human ability to encode, store, retain and subsequently recall past information and experiences in the brain. It is the sum of what we remember in total and allows us to learn and adapt from previous experiences and build relationships. Etymologically, the modern English word memoria originates from the handed down Latin word memoria and memor meaning aware and remembrance. In neurological and psychological terms, memory is simply classified as a set of neural connections encoded in the brain. Since the development of the computer in the 1940s, the word memory has also been used to describe a computer's ability to store information that would later be recalled, as well as the physical components of the computer in which that information is stored. the human brain is made up of 100 billion neurons. As you grow and develop, these neurons are connected to each other and communicate through thousands of connections called synapses. (sciencemuseum.org.uk) .The brain only reflects to process information that will be useful later and to let the rest, i.e. unimportant information, go unnoticed. Memories are formed when certain connections within our brains are strengthened. Human memory is a complex brain activity that allows us to store information and retrieve it again when we need it. All people have a natural curiosity about their own memory. This question was considered several years ago by reports in the popular press of recovered early childhood memories. This question also brought with it many other questions and whether children can recall memory for a certain period of time. This sudden interest in human memory led many to assume that the time had come for memory research. (Rovee-Collier, June 1999, p. 80) But this belief turned out to be wrong. The study of human memory dates back at least 20,000 years. Aristotle made one of the first attempts to understand human memory in his thesis entitled "On the Soul". In his thesis Aristotle compared the human mind to a blank slate and hypothesized that all human beings are born without constraints of any knowledge and are purely the sum of their experiences. He related memory to the rendering of signs in wax, which is sometimes spoken of as the “warehouse metaphor,” that is, a philosophy of memory, which has been kept wavering.
