  In response to this account, Prosser claims that Butler misreads Freud according to whom, he argues, the body ego really does arise from the body (1998, 40–2). Prosser appeals to Didier Anzieu's notion of the “skin ego”—the “inner experience” of the body arising from bodily sensations—which serves as a significant interface between psyche and body (65–67). This allows Prosser to argue that transsexuals appeal to the notion of the ‘wrong body’ because it simply feels that way (68–9). His account of body ego departs from Butler in emphasizing bodily sensation and proprioceptive awareness, rather than the visualization of bodily surface (78–9). Prosser deploys notions of bodily agnosia (the neurological inability to track parts of one's body) (78) and phantom limb experiences (84–5) to help explain the way in which a transsexual's body image may not accord with their actual body.
