In addition to the well-established involvement of descending neural tracts, the left-right side-specific endocrine mechanism may contribute to signaling from injured brain to spinal motor circuits.

The primary rhythm generators controlling respiration are integrated in a much larger network of brain regions, including areas not typically considered to be respiratory control centers, and that allow respiration to be adapted to all forms of ongoing behavior.

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

Differential, state-dependent occupancy of three discrete binding sites on α₁β₃ GABA_A receptors determines whether a specific neurosteroid analogue potentiates or inhibits GABA-elicited currents or competitively antagonizes neurosteroid action.

The Notch signaling pathway has a central role in the formation of the circuit that controls egg-laying in the nematode worm C. elegans.

Killer T cells swarm around tumour targets by accelerating the recruitment of distant T cells, which upon arrival and target engagement augment the chemotactic signal in a positive feedback loop.

Intersectional genetics show that excitatory neurons are essential for the functional and anatomical maturation of cerebellar circuits in mice.
