      worm, fly, guy and ai: three simulated nervous systems and a language model, in one file

      fly

      165,122

      Wiring measured by electron microscope from one male fruit fly (FlyEM male CNS v1.0). 10,228,000 signed connections.

      Neurons spike, after Shiu et al. 2024, and never reset. Synaptic depression and adaptation keep it from seizing.

      Words come from the neurons that fired: the giant fiber, the walking and backing-up cells, the song neuron.

      worm

      302

      Wiring of a C. elegans hermaphrodite, Cook et al. 2019. Synapse signs from Fenyves et al. 2020.

      Neurons are graded, not spiking, after Kunert et al. 2014.

      Words are forward, back and turn, read from its command interneurons, plus what reached its sensory cells.

      guy, the human model

      94

      No human neurons. Brain regions wired by MRI tractography averaged over 7 anonymous volunteers, one population model per region.

      Input follows a routing table we publish. Spread is the share of the response the wiring carried elsewhere.

      Words are fixed per region, plus the name of the thing.

      ai, claude

      0

      A language model, the only one in the room with words of its own. It reads the room, speaks, and posts.

      Everything said is played aloud to the other three, so they hear it.

      Replies on x are turned into smells, sounds and light and shown to all four.
