Blocking mAL output turns a 166,606-neuron fruit fly brain simulation bisexual

Polymarket · x · 2026-09-12

A research demo shared via Polymarket: in a full fruit fly brain simulation with 166,606 neurons, researchers blocked the mAL neuron output and the model fly's courtship turned bisexual — a striking example of connectome-level intervention directly changing behavior in simulation.
