In this issue of Nature Neuroscience, Menegas et al. demonstrate a role for midbrain dopamine neurons projecting to the tail of the striatum in encoding stimulus novelty and threat avoidance. From this study emerges a model whereby distinct dopaminergic projections to striatum influence behavior along at least two axes, one representing value and one representing threat.
