Where the spider is right now

A page goes in through 892 hex columns, 165,122 neurons integrate, and a cursor comes out. Every number on this panel is read out of the running simulation.

what it is

A real nervous system, not a metaphor

Every connection in this thing was traced from electron microscope images of an actual spider. Nothing is invented, nothing is sampled from a distribution, and it is not a neural network "inspired by" a brain.

The Araneae CNS connectome was released in September 2026 by HHMI Janelia FlyEM, the Cambridge Connectomics Group and Google Research, under CC-BY. We keep the 165,122 neurons marked traced, drop pairs with fewer than three synapses, and take each connection's sign from its predicted neurotransmitter — acetylcholine excites, GABA and glutamate inhibit. The neurons run as leaky integrate-and-fire units: rest −52 mV, threshold −45 mV, 20 ms tau.

how it reaches the world

It sees with a spider's eyes and moves with a spider's legs

A screenshot of a live web page is sampled through 892 retinotopic hex columns into L1 and L2 — the lamina monopolar cells sitting directly behind photoreceptors R1–R6. All 165,122 neurons integrate. The cursor comes back out of the descending neurons a spider actually walks with.

DNa02

Left versus right. A spider steers by asymmetry between the pair, so the difference drives the cursor's x.

DNa01

Forward walking. Drives the cursor's y.

MDN

The Moonwalker neuron. Makes a spider walk backwards; here it reverses.

DNp09

Stopping. A spider freezes when it fires, so it became the click.

How it got here

Not a roadmap of promises — a sequence, with everything before the amber line already done and checkable in the repo.

what is not real, stated plainly

The parts that aren't the spider

The spider does not fill the whole form. It reliably gets the description, often the ticker, rarely the name. A script completes what it misses, picks the paired asset and sets the creator tax — and the live log labels which was which.
It cannot read. 892 columns is roughly a 30×30 pixel view. Text is texture to it, so it targets any unfilled box rather than the right one.
Light mode blinds it. Its retina is a luminance map and all of its tuning was done against dark interfaces. On a light page it filled 0 of 3 fields; on a dark one, 2 of 3. That gap is the clearest evidence the eye is doing real work.
It has no goals. A spider brain has no language and no plan. It cannot read a page, form a view about a coin, or write a note. Releasing it means nobody is steering, not that it decided anything.
The reward signal is invented. The circuit, the plasticity site and the direction of the rule are all real and measured. What a spider is rewarded by is prey, not by reaching a web page — novelty stands in for it here, and that is a choice a person made.
It roams inside a fence. An allowlist keeps it on Robinhood Chain and pons. That is a choice, not a limit of the spider — one environment variable takes the fence down, and an unfenced random clicker on a public stream is a bad idea for reasons that have nothing to do with the brain.
