Eyewire Mystics should appreciate this study, which has some comparisons between drosophila and zebrafish!

This is great! I haven’t seen this study before. It’s interesting how such vastly different creatures can have such similarity in vision.


According to this study:

There are about 200k cells in the Drosphila’s brain and out of it, 100k are in the optic lobes.

Welcome back!

AFAIK, it’s a different project and it’s for a fly’s larva. It has “only” over 3000 neurons, while our drosophila has probably about 200k neurons. Quite a difference, I’d say. Yet, the larval project is still very interesting.

Hey! Right lol, i didnt look that much into it (neuron # diff. lol). Still interesting seeing similar projects from diff. labs.

yeah @Krzysztof_Kruk is right, that larval connectome is a few thousand neurons vs the whole fly brain being much larger. Also since it’s a larva (no legs or wings, just a tiny worm basically) it doesn’t exhibit most of the more complex behaviour that is studied in adults. Still, it’s impressive and important work. We’ll likely import the larval connectome into codex. Can let you guys know when it’s up if you’re interested in exploring.


Fun fact: adult Drosophila has more neurons than a larval zebrafish and more than a lobster.
Also more than a sponge, but that’s not hard to achieve :wink:
However, an elephant has almost 3 times more neurons, than a human. It’s almost the same difference as betweeen humans and gorillas (are we gorillas in the elephant world? :smiley: ).

those are some really cool stats! More than a lobster?!

Yeah, I was very surprised. But, lobsters are bugs of the sea, after all :smiley:
