The sensory homunculus is a model of the brain and body showing which sensory areas correspond to parts of the body.
The homunculus comes in two varieties-sensory and motor. The sensory homunculus shows how much brain power is dedicated to sensing different body parts. It looks weird because the relative proportions of the body parts are not about physical size, but the number of related neural connections in the brain.  Because of the fine motor skills and sense nerves found in these particular parts of the body they are represented as being larger on the homunculus. A part of the body with fewer sensory and/or motor connections to the brain is represented to appear smaller. Sensory homunculus: cortical homunculus, Motor Homunculus. This model shows what a man’s body would look like if each part grew in proportion to the area of the cortex of the brain concerned with its sensory perception.  The form of this model is distorted so we can see the relative sizes of the parts of the brain that correspond to parts of the body. SENSORY HOMUNCULUS: The sensory homunculus is a model of the brain and body showing which sensory areas correspond to parts of the body..  A homunculus (Latin for little man, plural: homunculi; from the masculine diminutive form of homo, man) is a representation of a small human being. Popularized in sixteenth century alchemy and nineteenth century fiction, it has historically referred to the creation of a miniature, fully formed human. References to the homunculus do not appear prior to sixteenth century alchemical writings; however alchemists may have been influenced by earlier folk traditions. A cortical homunculus is a physical representation of the human body, located within the brain. A cortical homunculus is a neurological map of the anatomical divisions of the body. There are two types of cortical homunculus; sensory and motor.  The sensory and motor homunculi Edit. Sensory and motor homunculi. The homunculus is also commonly used to describe the distorted human figure drawn to reflect the relative sensory space our body parts occupy on the cerebral cortex. Like the sensory homunculus, the motor homunculus looks distorted. For example the thumb which is used in thousands of complex activities appears much larger than the thigh with its relatively simple movement. The motor homunculus develops over time and differs from one person to the next. Body on the left side is the motor homunculus. The bigger the body parts in this picture are, more brainpower there is dedicated to controlling them. Positions of motor areas for these body parts can be seen on the top in the right hemisphere (left side of brain control the right side of the body and vise versa). To compare different areas, you may click on different parts of the picture. The body half on the right is sensory homunculus. The Homunculus. Scientists can map which parts of the brain control various parts of the body. The mapping is done by stimulating the sensory or motor cortex with a weak electric current. The stimulation often produces tingling or movement in part of the body.  The Mind/Body Link. The Sensory Homunculus is an image that shows the relative amount of cerebral cortex surface. area given over to processing the different sensory inputs and motor outputs of human nervous. system.  Motor/Sensory Homunculus To run the homunculus offline, you can download homunculus.jar. Should you have Java installed in your computer, you can run homunculus by double clicking the jar file you have downloaded. On-line version is not currently available. Positions of motor areas for these body parts can be seen on the top in the right hemisphere (left side of brain control the right side of the body and vise versa). To compare different areas, you may click on different parts of the picture. The body half on the right is sensory
