A sensory homunculus represents a map of brain areas dedicated to sensory processing for different anatomical divisions of the body. The primary sensory cortex is located in the postcentral gyrus, and …

The results of Penfield and Boldrey’s work suggested that the brain “sees” the human body very differently from the way the body appears physically. Penfield and Boldrey’s cortical homunculus …

Apr 21, 2023 · In my first neuroscience course at Columbia University, I learned about the homunculus. This “little man” is depicted as an upside-down representation of the human body moving from toe to …

Nov 25, 2025 · The homunculus is a specialized functional map, formally known as a somatotopic map, within the cerebral cortex. This concept reveals an orderly arrangement where adjacent body parts …

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

Jul 23, 2025 · Penfield’s investigations identified two distinct homunculi within the brain: the motor homunculus and the sensory homunculus. The motor homunculus is in the primary motor cortex, at …

The topographical representation of the homunculus is arranged in an anatomical fashion and represents the contralateral side. This means that the primary cortex in the right cerebral hemisphere …

Apr 19, 2023 · 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.

If you visually “map” body parts to the areas of the brain that control them, you end up with the illustration to the right. This visual representation of the brain’s map is called a homunculus, Latin for …

The concept has roots in preformationism as well as earlier folklore and alchemic traditions. The term lends its name to the cortical homunculus, an image of a person with the size of the body parts …
