In Chapter 9 of Writing Space, Jay David Bolter, writes about the homunculus:
This post will be talking about the homunculus from another perspective. When reading this chapter, I suddenly remembered learning about the homunculus in my Anatomy and Physiology class, so I wanted to do some research and recall the homunculus definition from the science perspective.
What I do recall prior to any research is the funny picture representation of the sensitivity of different sensory spots of the human body. The image to the right is a large scale version of the somatosensory cortex, which controls most of sense (primarily touch) reactions of the body.
In his article, "The Senses and Survuval: Using a Sensory Homunculus to Stimulate an Exploration of Adaptation," Paul Elliot notes, "A sensory homunculus is a two-or-three-dimensional reinterpretation of the human body designed to represent the area of the brain's sensory cortex receiving neurological input from different parts of the body's surface." The enlarged portions show more sensitivity to touch because they are "being served by a relatively large area of sensory cortex." (view the full article here)
I remember thinking the homunculus was an interesting concept and a good model for people who are visual learners, like I am. I also remember wondering how in the world we could have so much feeling in our lips and tongue, aside from taste. The homunculus can be startling to look at, but it is a "anatomy for dummies" way of understand the sensory layout of our bodies.

"The memory becomes a writing space, and the writer a homunculus who looks out at the world through our eyes and records what he sees. The homunculus translates perceptions into words and images and records them; he also puts down his inner thoughts and conclusions" (193-194).
