A retinal adrenergic module tunes mammalian visual evolution

How conserved neural circuits are modified during mammalian evolution remains poorly understood. Here we combine cross-species single-cell transcriptomics, in situ validation, retinal physiology, and conditional genetics to identify a superorder-associated adrenergic module in the mammalian retina. We find that ADRB1, which encodes the {beta}1-adrenergic receptor, is uniquely expressed in rod…
