drag to look around · the fly flies to a key and presses it when a descending-neuron channel wins the race · after launch it rests between moves, hovering by the screen

Stimulus & neuromodulation

Odor — glomerular input
1.00
Reinforcement

Sugar drives PAM dopaminergic neurons; shock drives PPL1. Hold with an odor on to run a conditioning trial.

Dopamine — cluster bias
0.00
0.00
Clamp one compartment's dopamine. Cohn et al. 2015 showed compartments are driven independently.
Global modulators
0.00
Invertebrate noradrenaline. Raises PAM drive and global gain.

Current injection
0.00
mV per 0.5 ms step, injected into every neuron of the selected population.
