    Decoding locomotion from population neural activity in moving C. elegans

    Kelsey M Hallinen, Ross Dempsey ... Andrew M Leifer
    Neurons in the brain exhibit activity with various relations to locomotion and these signals are best decoded by combining activities from many neurons.

    Neural population dynamics of computing with synaptic modulations

    Kyle Aitken, Stefan Mihalas
    Synaptic modulations alone imbue networks with computational capabilities comparable to recurrent connections on several neuroscience-relevant tasks, which manifest in fundamentally different neuronal dynamics.

    Modelling the neural code in large populations of correlated neurons

    Sacha Sokoloski, Amir Aschner, Ruben Coen-Cagli
    The proposed techniques enable researchers to disentangle the statistical features of neural population responses, and rigorously quantify how these features carry information about stimuli and experimental variables.

    Demixed principal component analysis of neural population data

    Dmitry Kobak, Wieland Brendel ... Christian K Machens
    A new data analysis tool provides a concise way of visualizing neural data that summarizes all the relevant features of the population response in a single figure.

    Stable task information from an unstable neural population

    Michael E Rule, Adrianna R Loback ... Timothy O'Leary
    Analysis and modelling of sensorimotor neural activity shows how ongoing plasticity and appropriately tuned weights can cope with substantial ongoing changes in the neural code.

    Neural population dynamics in motor cortex are different for reach and grasp

    Aneesha K Suresh, James M Goodman ... Sliman J Bensmaia
    The neuronal activity in primary motor cortex does not exhibit smooth low-dimensional dynamics during grasp as it does during reach.

    Homeostatic synaptic normalization optimizes learning in network models of neural population codes

    Jonathan Mayzel, Elad Schneidman
    An accurate and efficient biologically plausible statistical model of the spiking activity of neural populations shows computational benefits of homeostatic synaptic scaling in learning large neural population codes.

    Neural circuitry coordinating male copulation

    Hania J Pavlou, Andrew C Lin ... Stephen F Goodwin
    A circuit consisting of motor neurons, inhibitory interneurons and mechanosensory neurons controls copulatory behaviour in male fruit flies.
    1. Neuroscience

    Beta band oscillations in motor cortex reflect neural population signals that delay movement onset

    Preeya Khanna, Jose M Carmena
    Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.

    The neural crest is a source of mesenchymal stem cells with specialized hematopoietic stem cell niche function

    Joan Isern, Andrés García-García ... Simón Méndez-Ferrer
    Developing long bones contain distinct mesenchymal stem-cell populations derived from mesoderm and neural crest, which have specialized functions in skeleton formation and the establishment of the hematopoietic stem-cell niche, respectively.
