    Phase-amplitude coupling supports phase coding in human ECoG

    Andrew J Watrous et al.
    Electrocorticography (ECoG) reveals that phase-amplitude coupling relates to phase-dependent coding in the human brain.

    Learning improves decoding of odor identity with phase-referenced oscillations in the olfactory bulb

    Justin Losacco et al.
    Tetrode recordings show that the amplitude of gamma oscillations encodes for information on contextual odorant identity when observed at the peak phase of the theta oscillation in the olfactory bulb.

    A statistical framework to assess cross-frequency coupling while accounting for confounding analysis effects

    Jessica K Nadalin et al.
    A new measure for cross-frequency coupling assesses phase-amplitude coupling and amplitude-amplitude coupling, and accounts for confounding factors such as low-frequency amplitude fluctuations, using a flexible statistical modeling approach.

    A single regulator NrtR controls bacterial NAD+ homeostasis via its acetylation

    Rongsui Gao et al.
    Functional definition of NrtR and the discovery of its acetylation represents a first paradigm for linking protein acetylation to bacterial central NAD+ metabolism.

    IFN-mediated negative feedback supports bacteria class-specific macrophage inflammatory responses

    Rachel A Gottschalk et al.
    Inflammatory dynamics are tailored to bacterial class through macrophage integration of microbial stimuli and cytokine feedback.

    Possible magneto-mechanical and magneto-thermal mechanisms of ion channel activation in magnetogenetics

    Mladen Barbic
    Several new magneto-mechanical and magneto-thermal mechanisms of ion channel activation in magnetogenetics are proposed that may explain some of the mysteries that challenge current understanding of the magnetogenetics experiments.

    Astrocyte morphogenesis is dependent on BDNF signaling via astrocytic TrkB.T1

    Leanne M Holt et al.
    Brain-derived neurotrophic factor (BDNF)/TrkB.T1 signaling contributes to astrocyte morphological maturation, with implications for neuronal synaptogenesis and function and astrocyte functional maturation.

    Cerebellar folding is initiated by mechanical constraints on a fluid-like layer without a cellular pre-pattern

    Andrew K Lawton et al.
    A multi-phase wrinkling model accounts for the radial and circumferential tension and differential expansion between a uniformly proliferating outer fluid-like layer and an incompressible core that together drive cerebellar folding.

    Optogenetically induced low-frequency correlations impair perception

    Anirvan Nandy et al.
    Low-frequency correlations among neurons in monkey visual area V4 impair the animal's ability to perform an attention-demanding task, suggesting a causal role of these fluctuations in perception.
