===Topographic theory===
''Topographic theory'' was named and first described by [[Sigmund Freud]] in ''[[The Interpretation of Dreams]]'' (1899).<ref>Freud, Sigmund. 1955 [1915]. "The Unconscious." In [[The Standard Edition of the Complete Psychological Works of Sigmund Freud|''Standard Edition'']] 14, edited by [[James Strachey|J. Strachey]]. London: [[Hogarth Press]].</ref> The theory hypothesizes that the mental apparatus can be divided into the systems [[Consciousness|Conscious]], [[Preconscious]], and [[Unconscious mind|Unconscious]]. These systems are not [[Anatomy|anatomical]] structures of the brain but, rather, mental processes. Although Freud retained this theory throughout his life, he largely replaced it with the ''structural theory''.<ref name="Langs R 2010">[[Robert Langs|Langs, Robert]]. 2010.
