The authors study the lineal origins of norepinephrine (NE) neurons in the mouse hindbrain. They identify four genetically separable subpopulations of NE neurons, each with distinct anatomical location, axonal morphology and pattern of efferent projections. One unexpected finding is a projection to the prefrontal cortex that originates from outside the locus coeruleus.
