The ring
Compass cells sit on the outer ring, one arc per wedge of the ellipsoid body; the rest fill the inside. A neuron that fired on the last step is drawn bright.
A Drosophila head-direction ring attractor — 155 neurons, 6,522 connections — running as an organism on Nervos CKB. The fly is a cell: every tick consumes it and creates its successor, and the type script refuses anything that is not the exact result of the action the witness declares.
Every organism on this chain, found by asking for cells that wear the flybrain code. Each fly has a different type script, so there is no single script to look up. The eight-byte instance in the args is what makes two flies with the same genome two organisms — without it this list would have one row. Click a row to watch that one.
Compass cells sit on the outer ring, one arc per wedge of the ellipsoid body; the rest fill the inside. A neuron that fired on the last step is drawn bright.
CKB has no event log, and this is not one. It is the fly's chain of state cells, walked backwards from the current one, with each action read out of the witness the type script validated. Nothing here was emitted, and nothing here can be edited.
