- Historical Background
- Homunculus means "little man" in Latin
- Medieval and early modern times saw it as artificial human-like beings
- Early modern philosophers depicted it as tiny person in sperm
- Modern Cortical Homunculi
- Penfield and Boldrey introduced modern concept in 1937
- They mapped sensory and motor data from 126 surgical patients
- One-third of cortex dedicated to hands, another to face and tongue
- Artists created two separate three-dimensional homunculi
- Limitations and Accuracy
- Modern models oversimplify brain's actual processing of signals
- Cortical areas are not completely separated but interconnected
- Brain processes signals from both sensory and motor cortices
- Body part size doesn't determine cortical area extent
- Hands, face, and tongue receive most brain processing information
