Sensory Homunculus Diagram - Brain’s Body Map Explained #265285 (License: Personal Use)

The image depicts the sensory homunculus, a distorted human figure representing the relative amount of somatosensory cortex dedicated to processing touch from different body regions. Highly sensitive areas like the lips, fingers, and tongue appear enlarged, while less sensitive regions like the back or legs are minimized. This visualization underscores neuroplasticity and functional organization of the primary somatosensory cortex (Brodmann area 3, 1, 2).

Used in neuroscience education, medical textbooks, and psychology courses to teach cortical somatotopy; supports user intent for understanding brain anatomy, sensory processing, or neurology fundamentals.
