Where the monkey is looking right now

A web page goes in through 1,408 cells in V1, 32 areas integrate, and the gaze comes back out as a cursor. Every number on this panel is read out of the running simulation.

What it is

A monkey cortex, built from measurements

Its 32 areas, their layers and the wiring between them come from anatomy measured in macaque monkeys, assembled into one spiking network.

The multi-area model of macaque visual cortex was published in 2018 by Schmidt, Bakker, Hilgetag, Diesmann and van Albada. It covers 32 areas of one hemisphere, from V1 up to the frontal eye field and prefrontal area 46, with an excitatory and an inhibitory population in each of layers 2/3, 4, 5 and 6. At full scale that is 4.13 million neurons and 24.2 billion synapses. How many cells each layer holds comes from neuron density counts; how strongly the areas project to one another comes from retrograde tract tracing in macaques (Markov et al. 2014). This runs 2% of its neurons, 82,614 of them, each keeping a tenth of its synapses, scaled by the model's own rule. The neurons are leaky integrate-and-fire units: rest −65 mV, threshold −50 mV, 10 ms tau.

How it reaches the world

It sees through V1 and points with layer 5

A screenshot of a live web page is sampled by the 1,408 excitatory cells in layer 4 of V1, where the relay from the eye lands in a primate. All 32 areas integrate. The cursor is the gaze, and it comes back out of layer 5: the cells that project to the superior colliculus, which turns a place in the visual field into an eye movement.

V1, layer 4

Primary visual cortex, where the eye's signal arrives. Each excitatory cell looks at its own point of the screen and answers contrast, half to light and half to dark. This is the only way in.

V1, layer 5

Projects to the superior colliculus. Read as a population vector, where on the map its spikes landed, it carries most of a target's position to the cursor in this network.

LIP and FEF, layer 5

The lateral intraparietal area and the frontal eye field, the areas a macaque points its eyes with, read alongside V1.

Area 46, layer 5

Dorsolateral prefrontal cortex. Fire it hard while the gaze is still and the monkey is holding on something, so holding became the click.

The plan

How it got here

Not a roadmap of promises. A sequence, with everything before the gold line already built and checkable in the repo.

Launch a token on BNB Smart ChainIt fills the form on the launchpad and the click produces one signed transaction, from its own wallet, with nobody's hand on the pointer

Reward loop closedLayer 2/3 to layer 5 synapses under dopamine, in the frontal lobe where a primate's dopamine lands. Reaching somewhere new strengthens area 46; hitting a wall weakens the frontal eye field

Give it colourA macaque sees in three colours and this eye sees in one. Red-green and blue-yellow opponent channels into V1, so it can tell a gold button from a grey one
