Hexi nervous-system preview

The brain map, region colours, prompt flash and decay rules are adapted from
Hexi's own packages/bundle/src/nerves-view.js. The four recorded examples were
generated locally with Hexi's Brain implementation on a fresh connectome for
each input: prompt, success, error, and danger (0.9). They are sample responses,
not measurements of a visitor or activity on a visitor's computer. No user
session or personal data is included. The browser replays the sample readings.

The preview distributes only aggregate sample activity by region and drive,
not the connectome itself. Layout is adapted for the website; sample readings
are unchanged and the display fades them using Hexi's own timing rules.

Pictures of the nervous system (img/brain)

Drawn on 29 October 2026 from the same connectome: each dot is a neuron's cell
body at its recorded position. What is lit in each comes from Hexi's own code
run locally on that connectome: the neurons that fired in Hexi's Brain for a
success, an error, a touch, heat, a danger score of 0.8 and arousal; the
mushroom body's Kenyon-cell codes for example commands; the go/no-go gate's
settled outputs; and the populations nerves-body.js and nerves-mushroom.js
use. They are sample activity, not a visitor's, and contain no personal data.
