Build a brain. Explore its activity.
Simulate spiking microcircuits, watch deep nets learn, and explore synthetic fly, worm and mouse circuits alongside a human regional illustration. Stimulate regions and measure their responses on your own computer.
Free to explore every simulation — on your desktop or right here in your browser. Pro and Premium are one-time purchases and unlock both.

From one neuron to connected circuits.
Spiking Lab
Izhikevich neurons at 1 ms resolution. A 1,000-neuron cortical circuit that settles into alpha and gamma rhythms, synfire waves, a ring attractor that holds a memory, and a pattern generator that alternates like a walking gait.
Brain Console
Compare repeated, seeded trials across stimulus strengths with baseline, stimulation and recovery phases. Inspect spike rasters, firing-rate curves and trial variability. Adjust gains, noise and eligible STDP plasticity, save experiment projects and export measurements. An external readout can recall labels you teach from activity patterns.
Deep Nets
Design a network — inputs, up to six hidden layers, five activations — and train it live. Every neuron shows what it has learned as a map, next to the decision boundary and the loss curves.
Model choices in 3D
Choose a generated fly, worm or mouse circuit, or a human regional illustration with 288 population units. Stimulate regions and follow the activity. The human illustration is not an entire human brain or a neuron-level reconstruction.
Build your own
Pro adds the circuit editor: click to place neurons of seven firing types, drag to wire synapses, then let STDP learning reshape the weights. Save, reopen and export every spike.
Your computer, your data
Local simulations keep models and commands on your computer. Optional remote execution uploads the selected model and commands only when you connect to your chosen compatible service. No hosted simulation service is included.
Load a real brain wiring diagram.
Import FlyWire, neuPrint and other edge-list exports — .csv, .tsv or .csv.gz — with optional neuron annotations and selected IDs or regions for an induced subcircuit. Import labelled regional adjacency matrices with signed and fractional couplings for mammal and human population illustrations. Select the species for transmitter assumptions; dataset, release and selection notes stay with your import.
Models, clearly labelled
Bundled fly, worm and mouse circuits are synthetic. The human regional illustration uses spiking population surrogates, not a full human brain. Imported connectivity uses assumed Izhikevich dynamics and retains its own licence and citation. Activity and learned labels do not establish thinking, awareness or consciousness. Andromeda Neuro is for learning, research exploration and design — not medicine.

Install Andromeda Neuro
One installer for every edition — your licence key unlocks Pro or Premium. The 3D brain needs a graphics card or integrated GPU with up-to-date drivers.

Before you install
Are the bundled brain models real data?
The fly, worm and mouse circuits have generated connectivity. The human regional illustration uses 288 spiking population surrogates; it is not a reconstructed human brain or a calibrated neural-mass model. Import FlyWire or neuPrint exports for measured connectivity, which still needs assumptions about its dynamics.
Does Brain Console think or talk like ChatGPT?
No. It accepts experiment commands and reports measured circuit activity. Its external readout recalls labels you supply from spike patterns, without an LLM. That does not provide open-ended language or establish awareness or consciousness.
Can I run experiments remotely?
You can configure a compatible remote simulation endpoint and access token for Brain Console commands. Connecting explicitly uploads your selected model and subsequent commands to that service. Stimulus sweeps and project files currently run locally. Reference server code is provided for your own deployment; no hosted whole-brain simulation service is included.
Can I import a human regional connectivity matrix?
Yes. Import a square CSV or TSV matrix with matching row and column region labels, and choose which axis describes sources. Signed and fractional values become illustrative model couplings; each label becomes a generic spiking population surrogate. MRI connectivity values are not synapse counts, and this does not reconstruct individual human neurons or provide a calibrated whole-human-brain simulation.
Which neuron model does it use?
The Izhikevich (2003) model with seven firing types — regular spiking, bursting, chattering, thalamo-cortical, resonator, fast spiking and low-threshold spiking — stepped at 1 ms with delta or exponential synapses.
Can I use it without installing anything?
Yes. Open Andromeda Neuro in your browser: the Free edition works straight away, and Pro or Premium unlock when you sign in with the 14d.space account you bought them with, or when you paste your licence key. Simulations run on your own computer inside the browser tab. The desktop app adds remote simulation services and handles the largest whole-brain connectomes better.
How big a connectome can it run?
Pro imports up to 50,000 neurons; Premium up to 500,000 neurons and six million connections. Filter larger datasets to a selected circuit. Large circuits can run slower than real time on most computers.
Can I use it to control a robot?
Premium exports any connectome — synthetic or imported — as a plain JSON file with regions, neuron types, positions and signed weights, ready for your own controller code.
How do updates work?
Andromeda Neuro checks 14d.space for a newer verified release shortly after it starts and every four hours, and installs it when you close the app (Windows) or the next time you open it (Linux). Only packages signed by 14d.space are accepted.
What happens after the update year?
Your licence keeps working forever with every release from your update year.
