Sigmund Freud, “The Interpretation of Dreams”, 1899 was the topic of an earlier blog post. Here I present Sigmund Freud, “On Aphasia: A Critical Study”, 1891 a nonfiction medical book.  Anatomist had localized the language areas of the human brain to the left, cerebral hemisphere (in the top diagram of the left, hemisphere). “Arcuate fasciculus” is a nerve bundle connecting the language, expressive “Broca Area” into the language receptive “Wernicke Area” (shown in the labeled diagram below).  Sigmund Freud, was the first to go beyond neuroanatomy into “Psychiatry”.   Psychiatry is language-based medicine.  The neurolinguistics anatomy functions both in “wake (conscious)” and “sleep (unconscious)” daily cycling.  Aphasia is defined as the absence of internal language (called “endophasia”).  “Exophasia” in contrast. refers to language external to the body (commonly called “speech”).  Storytelling by a patient to a psychiatrist; allows  for the patient to have the psychiatrist in one’s mind.  Sigmund Freud, “On Aphasia: A Critical Study”, 1891 was among the first books by Doctor Freud.  “The Interpretation of Dreams”, 1899 is the book Sigmund Freud is most famous for; however, many of his later ideas can be traced to Sigmund Freud, “On Aphasia: A Critical Study, 1891.
