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 …

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

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 …

Brain Maps – The Sensory Homunculus Figure 2 (left) The mapping pattern of the visual field from the retina to the primary visual cortex.

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 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 …

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 …

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 …

All patient recordings were collated to obtain the first comprehensive map of motor and somatosensory localization in the human brain. This map was visualized as a distorted human-like figure—the …
