    Excitatory neurons in the preBötzinger Complex generate bursting activity responsible for breathing, but these alone cannot generate physiological breathing frequencies. Here the authors show how inhibition regulates refractory properties of excitatory neurons to allow dynamic breathing rhythms.

    The developmental origin and functional organization of the brainstem breathing circuits are poorly understood. Here using virus-based circuit-mapping approaches in mice, the authors reveal the lineage, neurotransmitter phenotype, and connectivity patterns of phrenic premotor neurons, which are a crucial component of the inspiratory circuit.

    Vocal communication is relatively common among fish: the midshipman being an example with a particularly wide dynamic range. In this paper, the authors demonstrate that different populations of hindbrain neurons are responsible for the frequency and duration of these calls.
