Wilder Penfield's homunculus

Wilder Penfield's homunculus is a visual representation of how different parts of the brain's motor and sensory areas correspond to specific parts of the body. It shows that areas controlling hands, lips, or face are much larger than those for other parts, reflecting their greater sensitivity or fine control. This map helps us understand how the brain processes sensations and directs movements, highlighting the disproportionate brain resources allocated to more sensitive or dexterous regions. It's a useful tool for studying brain functions and understanding neurological conditions.
