    The structural connectome constrains fast brain dynamics

    Pierpaolo Sorrentino et al.
    The fast spreading of neural activity across the brain has a complex structure, imposed by the white-matter bundles.

    Brain states govern the spatio-temporal dynamics of resting-state functional connectivity

    Felipe Aedo-Jury et al.
    Distinct brain states govern resting state functional architecture revealed by neurophysiologically defined simultaneous optic-fiber-based calcium recordings and task-free functional magnetic resonance imaging (fMRI) in rats.

    Phasic oxygen dynamics confounds fast choline-sensitive biosensor signals in the brain of behaving rodents

    Ricardo M Santos, Anton Sirota
    Fast fluctuations of oxygen, linked to behavioral and neural dynamics in vivo, cause phasic transients is amperometry-measured cholinergic signals via the mechanism of non-steady-state enzyme kinetics in the choline-oxidase-based biosensor.

    Filopodial dynamics and growth cone stabilization in Drosophila visual circuit development

    Mehmet Neset Özel et al.
    Long-term live imaging in intact developing Drosophila brains reveals a role for N-Cadherin-mediated fast filopodial dynamics and growth cone stabilization during neural circuit assembly.

    Subthalamic nucleus gamma activity increases not only during movement but also during movement inhibition

    Petra Fischer et al.
    Sudden stopping of rhythmic movement is associated with a pronounced increase of 60-90 Hz gamma oscillations in the subthalamic nucleus, which have formerly been regarded as favouring movement.

    Dynamic range adaptation in primary motor cortical populations

    Robert G Rasmussen et al.
    Motor neurons adjust their sensitivity to direction of movement in a manner analogous to how neurons in the visual system adjust their sensitivity to light.

    Common resting brain dynamics indicate a possible mechanism underlying zolpidem response in severe brain injury

    Shawniqua T Williams et al.
    The therapeutic effects of the sleeping pill zolpidem in patients with disorders of consciousness may be due to recruitment of brain cells idling in abnormally low-frequency brain waves.

    Tyramine induces dynamic RNP granule remodeling and translation activation in the Drosophila brain

    Nadia Formicola et al.
    Tyramine-dependent signaling triggers decondensation of neuronal RNP components and rapid translation activation of target mRNAs.

    Dopamine role in learning and action inference

    Rafal Bogacz
    A mathematical model describes the function of dopaminergic neurons in both learning and action planning.

    Irregular spiking of pyramidal neurons organizes as scale-invariant neuronal avalanches in the awake state

    Timothy Bellay et al.
    Spontaneous, irregular spiking in single cortical pyramidal neurons assembles as neuronal avalanches at the group level identifying a robust scale-invariant organization of resting activity in the awake state.
