    State-dependent activity dynamics of hypothalamic stress effector neurons

    Aoi Ichiyama, Samuel Mestern ... Wataru Inoue
    Hypothalamic stress effector neurons rapidly change activity patterns via recurrent inhibition, representing state-dependent activity switch between baseline and elevated stress levels.

    Human muscle spindles are wired to function as controllable signal-processing devices

    Michael Dimitriou
    By acting as versatile signal-processors that encode flexible coordinate representations, muscle spindles challenge current widely held views concerning the role of proprioceptors and the peripheral nervous system in sensorimotor function.

    UP-DOWN states and ripples differentially modulate membrane potential dynamics across DG, CA3, and CA1 in awake mice

    Koichiro Kajikawa, Brad K Hulse ... Evgueniy V Lubenov
    The majority of hippocampal neurons in CA3 experience inhibition before and during ripple buildup, while dentate and CA1 cells display depolarizing transients preceding and following ripple onset pointing to a long and orchestrated awake ripple initiation process.

    BK channel properties correlate with neurobehavioral severity in three KCNMA1-linked channelopathy mouse models

    Su Mi Park, Cooper E Roache ... Andrea Meredith
    Among three new models for KCNMA1 channelopathy, the most severe gain-of-function variant (Kcnma1N999S/WT) displays a particular type of immobilizing paroxysmal dyskinesia observed in patients, including amphetamine responsiveness.

    Age-associated changes to neuronal dynamics involve a disruption of excitatory/inhibitory balance in C. elegans

    Gregory S Wirak, Jeremy Florman ... Christopher V Gabel
    Comprehensive multi-neuron fluorescence imaging in C. elegans reveals age-associated changes in neuronal activity that include a breakdown of system-wide organization, changes in neuronal frequency dynamics, and a disruption of the balance between excitatory and inhibitory signaling.

    Circadian programming of the ellipsoid body sleep homeostat in Drosophila

    Tomas Andreani, Clark Rosensweig ... Ravi Allada
    The circadian clock gates sleep drive by modulating sleep homeostat neurons.

    Intact Drosophila central nervous system cellular quantitation reveals sexual dimorphism

    Wei Jiao, Gard Spreemann ... Brian D McCabe
    Fewer neurons and more glia than previously predicted plus substantial differences between males and females are revealed when entire intact Drosophila larval central nervous systems are quantified using a synthesis of genetic, imaging, and computation technologies.

    Predictions and experimental tests of a new biophysical model of the mammalian respiratory oscillator

    Ryan S Phillips, Hidehiko Koizumi ... Jeffrey C Smith
    The predictive power of a computational model advances understanding of the neuronal and circuit biophysical mechanisms that generate the respiratory rhythm and neural activity patterns in the mammalian brainstem.

    Sigma oscillations protect or reinstate motor memory depending on their temporal coordination with slow waves

    Judith Nicolas, Bradley R King ... Genevieve Albouy
    Sigma oscillations have a dual role in motor memory consolidation depending on their temporal coordination with slow waves during post-learning sleep.

    Cognitive experience alters cortical involvement in goal-directed navigation

    Charlotte Arlt, Roberto Barroso-Luque ... Christopher D Harvey
    The areas of the cerebral cortex that are necessary for mice to perform goal-directed navigation differ depending on previous experience in cognitively challenging tasks.
