What will be an ideal response? Title: 8-115. Explain what is meant by the term motor homunculus. Post by: -justin- on Jan 19, 2018 Answer: The primary motor cortex lies just before the central sulcus on each hemisphere. The motor cortex is organized in a topical fashion such that activation of certain patches of cortex results in movements of particular parts of the body. The homunculus is a cartoon representation of the topical organization of the motor cortex. In effect, it resembles an upside down person with the legs over the top of the cortex and the face at the bottom of the motor strip.
