holy shit i am learning that there is a worm that is 1mm long called the caenorhabditis elegans that has so few cells in it's body that it's known and documented what EACH of the <1000 CELLS is and does??? it's brain only has 302 neurons which means apparently they're not far off from being able to record this thing's complete neural activity.
where this is going is a project called OpenWorm which looks like an attempt to digitally simulate the entire physical+neural workings of this worm??
here's the OpenWorm Wikipedia and their website
