Sensory Homunculus and Brain Mapping - Understanding Body Representation in the Cortex #265279 (License: Personal Use)

This composite image pairs a classic sensory homunculus diagram-showing distorted proportions based on neural innervation density-with a real human brain specimen, where a dotted line marks the primary somatosensory cortex region corresponding to genitalia. The homunculus emphasizes areas with high tactile sensitivity (e.g., fingers, lips), while the photo provides anatomical context for neuroanatomical study.

Used in neuroscience education, medical textbooks, and online learning modules to explain somatosensory mapping; targets students, clinicians, and curious learners seeking foundational knowledge of brain organization and sensory processing.
