The hypothalamus contains the highest diversity of neurons in the brain, which use-dependently co-release neurotransmitters and neuropeptides. Investigators have hitherto relied on candidate protein-based tools to correlate behavioral, endocrine and gender traits with hypothalamic neuron identity. Here, we mapped neuronal identities in the hypothalamus by single-cell RNA-sequencing. We distinguish 62 neuronal subtypes producing glutamatergic, dopaminergic or GABAergic codes for synaptic neurotransmission and harboring the ability of task-dependent neurotransmitter switching. We identify dopamine neurons that uniquely co-express Onecut3 and Nmur2 genes, and place these in the periventricular nucleus with many synaptic afferents arising from neuromedin S+ neurons of the suprachiasmatic nucleus. These neuroendocrine dopamine cells may contribute to the dopaminergic inhibition of prolactin secretion diurnally because their neuromedin S+ inputs originate from pacemaker 2/3 (Per2/3)-expressing neurons and their tyrosine hydroxylase phosphorylation is circadian regulated. Overall, our catalogue of neuronal subclasses presents new understanding of hypothalamic organization and function.
