Introducing the Horse-unculus!

In the world of neuroscience, researchers and instructors have developed the “homunculus” to show through exaggerated size screen-shot-2016-11-15-at-3-51-34-pmthose areas of the human body which we know to have a greater representation of neurons in the somatosensory cortex in the brain, the main sensory receptive area for the sense of touch. Check out the image at right.

The Horse-unculus is a model developed by BestHorsePractices to illustrate through exaggerated size and shining light those areas which we know to be more sensitive, ie, having a greater representation in the somatosensory cortex of the horse’s brain. This understanding will be discussed by Dr. Steve Peters at the Evidence-Based Horsemanship Seminar later this week.

Areas of high sensitivity include the entire head, especially the muzzle area (which is loaded with vibrissae, or whiskers, each of which has its own nerve). Horse’s eyes, ears,  tongue, and nose are represented by larger portions of the somatosensory cortex as these areas are densely populated with sensory nerves.

Withers, lower flank, and where the hoof wall meets the hairline are additional areas that have greater representation in this part of the brain. The horse-unculus highlights through exaggerated size and brighter color those noted areas.

  • Interesting read. I know that Dr. Peters and Martin Black as they explain to bigger and bigger audience their message finally will reach out
