This is a data-derived research explorer—not the illustrated model. Search the complete retained neuron catalog, inspect real morphology, follow strong connections and save a reproducible local stress test.

Complete soma-position view
See every indexed neuron.
This lightweight view indexes all 166,700 records and plots the 140,638 neurons with published soma coordinates. It is a complete position map—not complete axonal, dendritic or synaptic morphology. The other 26,062 records remain searchable without invented locations. Open the official full-detail model ↗

Reproducible local experiment
Connection stress test
Reduce the selected neuron’s displayed connection weights and compare the remaining local signal capacity. This does not simulate Alzheimer’s pathology.

Data and method
Built to be inspectable.
The catalog preserves every superclass-annotated neuron in the checksum-pinned flybrain 0.1.0 brain-v1 build. The site loads only the shard needed for the selected neuron.
Connectivity is limited on screen to the strongest 18 incoming and outgoing normalized model weights. That keeps the interface usable without implying those are the neuron’s only biological synapses.
