Furthermore, there are real homunculi in your brain. For example, there is a motor homunculus, a motor strip in your cortex that actually does map to your body. These are real connections. Those brain cells give off axons that actually go to all parts of the body through the spinal cord and nerves. Developmentally, this is called somatotopic mapping. When the brain is forming, it maps itself to neurons connecting to other parts of the body, along both the motor and sensory strip. This also works for the retina, which maps to the visual cortex. We can see the brain’s homunculi when we map the
