Conjecture: There are elemental abstractions
Neuronal structure is conserved
- Insects, invertebrates, mammals have neurons
- Brain regions used for one function can co-opt other functions
- Mammals have similar brains
-
Neuronal signaling is conserved
- Across brain regions and across the animal kingdom
- Action potentials, neurotransmitters
- Unclocked, asynchronous, parallel
