Is it reasonable to expect that as this science progresses, it will progressively map out more complex connectomes? So the connectomes of nematodes and sea squirts have only a few hundred neurons each; and a fruit fly larva has 3,016 neurons with 548,000 synapses; and humans have 86 billion neurons with hundreds of trillions of synapses; is the expectation that brain maps will progressively be made of animals that have: 10k neurons - e.g. leech [1] 100k neurons - e.g. lobster [1] 1M neurons - e.g. cockroach [1] 10M neurons - e.g. zebrafish [1] 100M neurons - e.g. mole-rat [1] 1G neurons - e.g. buzzard [1] 10G neurons - e.g. giraffe [1] [1] https://en.wikipedia.org/wiki/List_of_animals_by_number_of_neurons https://en.wikipedia.org/wiki/List_of_animals_by_number_of_n...
