ï»¿The Man Who Mistook His Wife for a Hat ———. 1967b. “Fat Transport in Lipoproteins—An Integrated Approach to Mechanisms and Disorders.”New England Journal of Medicine. Jan. 26; 276(4):215–25. In the 1960s, during a period of experimenting with large doses of amphetamines, I experienced a different sort of vivid mental imagery. Amphetamines can produce striking perceptual changes and dramatic enhancements of visual imagery and memory (as I described in“The Dog Beneath the Skin,” a chapter inThe Man Who Mistook His Wife for a Hat). For a period of two weeks or so, I found that I had only to look at an anatomical picture or specimen, and its image would remain vivid and stable in my mind for hours. I could mentally project the image onto a piece of paper—it was as clear and distinct as if projected by a camera lucida—and trace its outlines with a pencil. My drawings were not elegant, but they were, everyone agreed, quite detailed and accurate. But when the amphetamine-induced state faded, I could no longer visualize, no longer project images, no longer draw—nor have I been able to do so in the decades since. This was not like voluntary imagery—I did not summon images to my mind or construct them bit by bit. It was involuntary and automatic, more akin to eidetic or “photographic” memory, or to palinopsia, an exaggerated persistence of vision. 26“I just disagree with this” […] “don’t worry about it.”: Susan Mulderick’s interview with state investigators January 1, 2006. Kathleen Fournier’s recollections when she spoke with state investigators the following month were similar, as described in more detail in Chapter 8. Fournier did not respond to requests to speak with the author or offers to fact check the material in this book. The author attempted to verify the accounts through other sources, as described in these Notes.
