The paper presents a system for high-resolution kinematic and muscle activity measurement in freely behaving flies using closed-loop tracking and pose estimation.

The paper identifies three genetic dopamine subtypes in the substantia nigra pars compacta, each with distinct functional responses to rewards, aversive stimuli, and movement, showing strong correlation between soma and axon signaling within subtypes.

The paper shows that somatic and axonal signaling in dopamine neurons of behaving mice are correlated, challenging previous assumptions about axonal autonomy.
