    Biophysical mechanisms in the mammalian respiratory oscillator re-examined with a new data-driven computational model

    Ryan S Phillips et al.
    Computational modeling motivated by recent experiments clarifies biophysical mechanisms generating the rhythm and amplitude of breathing at the level of neurons and brain circuits in mammals.

    Atoh1-dependent rhombic lip neurons are required for temporal delay between independent respiratory oscillators in embryonic mice

    Srinivasan Tupal et al.
    The rhythmic patterns of activity that underlie breathing are generated and coordinated by distinct populations of neurons within the brainstem.

    The retrotrapezoid nucleus neurons expressing Atoh1 and Phox2b are essential for the respiratory response to CO2

    Pierre-Louis Ruffault et al.
    The location of neurons responsible for increasing the breathing rate upon detecting elevated levels of CO2 in the blood has been pinpointed to the retrotrapezoid nucleus in the brainstem.

    Interactions between respiratory oscillators in adult rats

    Robert TR Huckstepp et al.
    Active expiration in anesthetized rats is driven by the lateral parafacial region, but requires an additional form of excitation from another source.

    CO2-evoked release of PGE2 modulates sighs and inspiration as demonstrated in brainstem organotypic culture

    David Forsberg et al.
    Novel brainstem organotypic cultures that generate rhythmic respiratory motor activity reveal the neural networks that control breathing and a new pathway in the hypercapnic response.

    Laser ablation of Dbx1 neurons in the pre-Bötzinger complex stops inspiratory rhythm and impairs output in neonatal mice

    Xueying Wang et al.
    Laser-ablating neurons of a single genetic class reveals that Dbx1-derived interneurons comprise core respiratory rhythmogenic and premotor circuits and provides quantitative cellular parameters that govern network functionality

    Mixed-mode oscillations and population bursting in the pre-Bötzinger complex

    Bartholomew J Bacak et al.
    Computational modeling reveals the mechanisms by which a diverse group of neurons in the brainstem generates rhythmic breathing in mammals.

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.

    Speed and segmentation control mechanisms characterized in rhythmically-active circuits created from spinal neurons produced from genetically-tagged embryonic stem cells

    Matthew J Sternfeld et al.
    Stem cell derived ventral-spinal cord excitatory neurons self-assemble into a rhythmically bursting neural network whose speed and intercellular coordination are both instructively modulated by cell-type specific interactions with inhibitory neurons.

    Opioids modulate an emergent rhythmogenic process to depress breathing

    Xiaolu Sun et al.
    Inspiratory rhythmogenesis is mediated by an emergent mechanism independent of bursts associated with motor output and is modulated by opioids, pointing to strategies for ameliorating opioid-induced respiratory depression.
