He’s a guy who mapped out two Homunculus by probing down parts of the Frontal and Parietal Lobes
Cortical Maps
- Penfield’s cortical stimulation: mapped motor and sensory homunculi.
- Motor cortex (precentral gyrus).
- Somatosensory cortex (postcentral gyrus).
- Representation proportional to sensitivity/motor control (e.g., hands, lips overrepresented).
- Brodmann’s areas: 52 regions based on cytoarchitecture (e.g., area 17 = primary visual, area 4 = primary motor, areas 1–3 = somatosensory).
