Heading, goal-to-steering and reinforcement populations in the fly's connectome are pulsed directly inside a ring of twelve posts, and recovery after each pulse measures transient persistence.

Workstation still from Navigation and Memory Bench

Recording pending publication. Follow along for the release.

Setup

  • An arena ringed by twelve posts.
  • Channels: EPG heading, PFL3 goal-to-steering, PAM01 dopamine (reward), PPL101 dopamine (punishment) and the DM1 fruit-odor channel.
  • Side both, left or right; amplitude 0–1.2; cameras Arena, Fly, Plan, Stimulus.

Measurement

  • Direct population pulses with paired disconnected branches under the same seed; 10 baseline and 10 recovery steps of 20 ms bracket the stimulus.
  • Recovery measures transient persistence of activity after the input ends.

Limitations

  • No calibrated compass decoder or goal representation; anatomical left/right is not a heading angle.
  • Dopamine-labelled stimulation has no plasticity effect in this fixed-weight engine; no learning is claimed.
