0xbrain — an autonomous digital connectome doomscrolling the web
A complete nervous system runs live in your browser. Every neuron integrates, leaks and fires in real time; its motor neurons steer a simulated Chromium window through feeds, forums and articles. Nobody drives it. It learns what to look at on its own through spike-timing dependent plasticity, gated by a dopamine signal that rewards novelty.
The page under its cursor, and the brain driving it
Left: the browser the agent is steering. Right: the same instant inside its connectome — every sphere a neuron, every line a synapse carrying a spike.
MN1/MN2 pull left, MN4/MN5 pull right, MN3 sets gain. Their instantaneous firing rates are integrated into a velocity vector that moves the pointer.
The ddN escape interneuron fires when sensory contrast spikes past threshold. That single spike becomes a mouse-down; novelty then floods dopamine back.
Twelve live surfaces: Hacker News, Reddit, arXiv, YouTube, X, GitHub, Nature and tech press. Scroll depth, headline density and luminance are its only senses.
The agent moves as its cursor moves on the page: left–right is left–right, depth is how far down the feed it has scrolled. Every dot is one real cell at its measured position in the wiring diagram.
Green sensory cells fire first, relays carry charge back to the motor ganglion, interneurons decide, and motor neurons drive the muscle bands. Drag to orbit, scroll to zoom, click a cell to read its record.
Click any neuron in the tank to read its wiring record: class, transmitter, and the exact cells feeding into and out of it.
Dorsal schematic & real-time readouts
Nothing here is pre-rendered. Every pixel is drawn from the same membrane state that is driving the cursor above.
What it is doing, as it does it
Every line is emitted by the simulation itself — sensory events, spikes, motor commands, behavioural decisions and learning updates.
Where it keeps going back to
Preference is not configured. It emerges from dwell time, revisit rate and the dopamine it received the last time it was there.

How 0xbrain actually works
No language model. No prompts. A biologically-grounded spiking network wired to a browser, learning from its own timing.
The connectome
The substrate is a fixed wiring diagram: 177 cells across sensory, relay, interneuron, motor and muscle bands, joined by 6,618 directed chemical synapses and 1,206 bidirectional gap junctions. Topology never changes — only the weights do.
Leaky integrate-and-fire
τ_m · dV/dt = −(V − V_rest) + R·I(t)
if V ≥ V_th: emit spike, V ← V_reset
refractory for t_ref = 2 msτ_m = 45 ms, V_th = 1.0 normalised, synaptic current decays with a 30 ms exponential kernel.
STDP with dopamine
Δw = A₊·e^(−Δt/τ₊) if Δt > 0 Δw = −A₋·e^(Δt/τ₋) if Δt < 0 w ← w + D(t) · e_ij(t)
e_ij is the eligibility trace; D(t) is the dopamine level released when the agent lands somewhere novel. Reward is curiosity, not clicks-per-second.
Load the full wiring diagram — 177 neurons, 6,618 chemical synapses, 1,206 gap junctions — into typed arrays and assign resting potentials.
