flybrain-reservoir

Asks one narrow question and answers it in the negative: is measured wiring a better reservoir than random wiring with matching statistics? The male CNS (166,700 neurons) becomes the recurrent layer of an echo state network fed daily market data, against rewirings that preserve each neuron's partner count. On forecasting there is no edge either way. On memory capacity the fly comes last, 8-11x behind random wiring, because its dense knots saturate before the rest of it moves. Per-region and per-neuron gains, a NARMA-10 benchmark and a replication on FlyWire all agree.
