hoodcat: a rat brain.
103,200 spiking neurons rebuilt from rat neuroanatomy,wired to a live meme-coin market on robinhood chain.
it smells. it decides. it trades. nobody steers it.
the cat is the face. the tissue is a rat's, and it is the only thingthat decides anything here.
running in paper mode since 2026-09-13. every number on this page ismeasured — including the ones that say it doesn't work yet.

no model. no backprop. no prompt. one differential equation per neuron,solved 2,000 times per simulated second on a consumer gpu.
the market becomes a smell: 8 normalised features per token, encoded aspoisson spike trains into the sensory cortex. what comes out the otherend is three competing populations of neurons. the loudest one acts.

verdict: it perceives. it does not yet act on what it perceives.the signal dies between L4 and L5. we measured where. we are fixing it.

per-column L2/3 and L5 rates are not published by the brain yet.
colony
the same brain, 5,300 neurons of it, is yours to make. six sliders,and each one is a real parameter of the tissue — not a label on a profile.
| slider | measured over 200 ticks | 95% CI |
|---|---|---|
| impulsive | acts on 27.7% → 66.0% of ticks | [+0.323 ; +0.441] |
| greedy | mean mood -0.59 → +0.35 | [+0.938 ; +0.938] |
| curious | mood +0.14 → -0.40 | [-0.544 ; -0.544] |
| nervous | striatal margin 1.71 → 2.22 Hz | [+0.388 ; +0.625] |
| grudge | dips -1.00 → -0.41, our guess was wrong | [-0.104 ; -0.104] |
| clingy | comfort 0.61 → 0.97, willingness +0.001 | [+0.367 ; +0.367] |

48 cats, 6 sliders × 2 groups × 4 seeds, 200 ticks of the recorded market.nearest-centroid separability 1.00 for all six — and two of the six say weguessed wrong, which is why they are still on this page.
→ make one it lives in the same market as the big one
a cat of yours never trades. it watches, it has an opinion, and itanswers you only when it feels like it.
