Combining rabies-virus tracing, optical clearing (CLARITY), and whole-brain light-sheet
imaging, we mapped the monosynaptic inputs to midbrain dopamine neurons projecting to …

Opposite initialization to novel cues in dopamine signaling in ventral and posterior striatum in mice

W Menegas, BM Babayan, N Uchida… - elife, 2017 - elifesciences.org
Dopamine neurons are thought to encode novelty in addition to reward prediction error (the
discrepancy between actual and predicted values). In this study, we compared dopamine …

Multi-animal pose estimation, identification and tracking with DeepLabCut
