The homunculus is commonly used today in scientific disciplines such as psychology as a teaching or memory tool to describe the distorted scale model of a human drawn or sculpted to reflect the relative space human body parts occupy on the somatosensory cortex (the sensory homunculus) and the motor cortex (the motor homunculus).

A cortical homunculus (from Latin homunculus 'little man, miniature human'[1][2]) is a distorted representation of the human body, based on a neurological "map" of the areas and portions of the human brain dedicated to processing motor functions, and/or …

Homunculus, diminutive fully formed human body, historically believed to inhabit a germ cell (an egg or a sperm) and to have the capacity to increase in size, giving rise to an adult human. The word homunculus is Latin for “little man” or “little person.”

2023年7月24日 · The sensory homunculus is a topographic representation of the sensory distribution of the body found in the cerebral cortex. This topograph usually has body parts illustrated along the surface of the postcentral gyrus of the parietal lobe. The topography of the sensory homunculus corresponds to the contralateral side of the body.

2024年9月30日 · The sensory homunculus resides in the Brain Somatosensory Cortex: Mapping Sensations in the Human Brain, a strip of brain tissue running from ear to ear across the top of the head. This area is responsible for processing sensory information from all over the body.

皮质小人 （英語： cortical homunculus）是一种绘制人体的特殊方式，其中人体不同部分的比例并非按真实比例确定，而是对应着 大脑 中负责该部位运动与感官功能的区域的大小。 Homunculus 为 拉丁语 中“小人”之意。 皮质小人包括运动小人（motor homunculus）与感官小人（sensory homunculus）两种。 运动小人 对应着负责人体各部位运动功能的脑区。 大脑的 初级运动皮层 位于中央前回，处理从 额叶 前运动区 传入的信号。 [1] 感官小人 则对应着负责各部位感官功能 …

2017年10月27日 · In the Middle Ages, a homunculus was an artificial humanoid created through alembics and mysterious alchemy. In modern times, Penfield and Boldrey brewed their own version of the homunculus using more controlled, though no less controversial, ingredients. Their approach was systematic and laborious.

The homunculus, a ‘grotesque creature’ depicting the proportional representation of the human body on the primary somatosensory cortex, is a most influential discovery in neuroscience. A new study reveals that these proportions substantially differ between different cortical regions, in view of their functional specialization.

2022年6月9日 · Understanding the somatosensory homunculus has helped develop treatments for conditions like phantom pain and brain tumors. However, as Preston Foerder, assistant professor of psychology at the University of Tennessee at Chattanooga (UTC) often tells his students: You never see a female homunculus.
