    MDN brain descending neurons coordinately activate backward and inhibit forward locomotion

    Arnaldo Carreira-Rosario et al.
    A brain descending interneuron can coordinate a switch between two antagonistic behaviors (forward and backward locomotions).

    Work minimization accounts for footfall phasing in slow quadrupedal gaits

    James R Usherwood, Zoe T Self Davies
    The range of footfall patterns seen in walking amphibians, reptiles and mammals, including hippopotamus, horse and (inverted) sloth, are consistent with simple principles of mechanical work minimization.

    Analysis of the NK2 homeobox gene ceh-24 reveals sublateral motor neuron control of left-right turning during sleep

    Juliane Schwarz, Henrik Bringmann
    A genetic analysis has identified the cholinergic SIA sublateral motor neurons, which innervate all four body wall muscles separately, as crucial regulators of turning around during sleep in Caenorhabditis elegans.

    Resolving coiled shapes reveals new reorientation behaviors in C. elegans

    Onno D Broekmans et al.
    A conceptually simple algorithm can analyze previously uncharacterized 2D coiled postures of the nematode C. elegans and has uncovered new reorientation behaviors in large amplitude turns.

    Functionally asymmetric motor neurons contribute to coordinating locomotion of Caenorhabditis elegans

    Oleg Tolstenkov et al.
    The 'missing' class of Caenorhabditis elegans excitatory motor neurons, AS, contribute to propagation and coordination of body waves, integrating information from, and feeding back to premotor interneurons byelectrical signaling.

    Nociceptive interneurons control modular motor pathways to promote escape behavior in Drosophila

    Anita Burgos et al.
    A class of interneuron is identified that promotes escape behavior downstream of nociceptor inputs via connections to nociceptive integrator and premotor networks.

    Distributed rhythm generators underlie Caenorhabditis elegans forward locomotion

    Anthony D Fouad et al.
    The forward locomotor circuit of the roundworm Caenorhabditis elegans consists of multiple rhythm-generating units coupled to one another in a bidirectional manner.

    A circuit mechanism for the propagation of waves of muscle contraction in Drosophila

    Akira Fushiki et al.
    Coordinated activation and deactivation of inhibitory neurons triggers sequential muscle contractions that enable fruit fly larvae to propel themselves backwards and forwards.

    Neuromodulatory connectivity defines the structure of a behavioral neural network

    Feici Diao et al.
    Using targeted functional manipulations of neural activity to map neuromodulatory connections can deliver considerable insight into the functional architecture of a behaviorally important network even in the absence of information about its synaptic connectivity.

    A spiral attractor network drives rhythmic locomotion

    Angela M Bruno et al.
    The neural population of the Aplysia's pedal ganglion are a low-dimensional spiral attractor, and the parameters of the attractor directly define the properties of the Aplysia's escape locomotion behaviour.
