Episode notes
Mobius Strip Form and Function
- A Mobius strip's shape changes when made from elastic material and relaxed to its lowest energy state.
- This reveals new aspects of form and function beyond traditional topology.
Physical Basis of Brain Folding
- Brain folding arises from swelling of outer layers compared to inner layers, creating compression and folds.
- Physical gel experiments mimic brain cortex folding, connecting form to function.
Function Drives Biological Folding
- Brain and organ folds serve functional roles like optimizing surface area and wiring length.
- Folding and brain functionalization likely develop together from a mix of genetic pre-patterning and self-organization.
