Penfield's homunculus

Penfield's homunculus is a visual representation of how different parts of the brain's sensory cortex correspond to sensations in specific body areas. It shows that the brain allocates more processing space to regions like the hands and face, which are more sensitive and require fine control. This map helps us understand how the brain perceives touch and sensation, highlighting the uneven distribution of sensory input across different body parts. Essentially, it illustrates that some parts of our body have a larger "brain area" devoted to sensing them, reflecting their importance in our daily experiences.
