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 …

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12月23日 · 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.”

2024年9月30日 · Explore the fascinating concept of the homunculus brain, its role in sensory and motor functions, neuroplasticity, and its implications for neuroscience.

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.

Penfield’s description of the ‘homunculus’, a ‘grotesque creature’ with large lips and hands and small trunk and legs depicting the representation of body-parts within the primary somatosensory cortex (S1), is one of the most prominent contributions to the neurosciences.

2018年8月16日 · A homunculus is a topographical-organized map of the proportional representation of the contralateral somatosensory or motor neurons on the cortex or passing though a part of the brain. The maps are often comical, as the body parts are disproportionally represented compared to their physical size.

2023年4月19日 · Found in countless textbooks, it depicts a deformed constellation of body parts mapped onto a narrow strip of the brain, showing the corresponding brain regions that control each part. But a...

2023年3月17日 · You can find the homunculus in the somatosensory cortex, part of the brain responsible for processing and interpreting sensory information from the body.

The somatosensory homunculus is a representation of the human body in the brain’s somatosensory cortex. The term homunculus comes from the Latin word for “little man” and refers to a map of the human body that is laid across a portion of the cerebral cortex.
