The combination of single-cell transcriptomics and whole-brain mapping of bulk and single-cell projections reveals the relationship between the molecular architecture, cell body distribution, and axonal arborization of serotonin neurons.

Dorsal raphe Pet1 neurons are molecularly heterogeneous, comprising as many as fourteen distinct subtypes that show biased cell body distributions across dorsal raphe subdomains.

A hub in the rostral anterior cingulate cortex receives unusually high and functionally diverse inputs, providing a biological interface between motivation, incentive based learning, and decision making.

The Eyeless/Pax6 temporal transcription factor generates neuronal identity, connectivity, and flight navigation behavior within the conserved adult brain structure called the central complex.

Gut-innervating sensory neurons detect large food volumes and inhibit feeding in Drosophila through the mechanically gated ion channel Piezo.

The discovery of markers specific to perisynaptic Schwann cells will accelerate the discovery of mechanisms important for their differentiation and function.

A new resource of transgenic zebrafish lines facilitates precise targeting of neuronal cell-types within the brain, supported by online software for visualizing transgene expression patterns.

Sex-specific characteristics of the fruit fly courtship behavior are not specified by a single binary switch, but as a combination of traits that are modularly specified by separable genetic switches.

Genetic analyses combining photoconvertible cell signalling reporters with gain- and loss-of function manipulations reveal a novel role for Notch signalling in controlling Hedgehog response in neural progenitor cells.

The first survey of the complete morphologies of nerve endings in the skin of mice has revealed enormous structural diversity.
