    Phase-amplitude coupling supports phase coding in human ECoG

    Andrew J Watrous, Lorena Deuker ... Nikolai Axmacher
    Electrocorticography (ECoG) reveals that phase-amplitude coupling relates to phase-dependent coding in the human brain.

    Stimulus background influences phase invariant coding by correlated neural activity

    Michael G Metzen, Maurice J Chacron
    Building on previous work (Metzen et al., 2016), a combination of neurophysiological and behavioral approaches reveals that changes in the background strongly impacts invariant coding and perception of behaviourally relevant signals.

    Neuronal sequences during theta rely on behavior-dependent spatial maps

    Eloy Parra-Barrero, Kamran Diba, Sen Cheng
    A computational framework and analysis of rodent CA1 data reveals that theta oscillations sequentially sweep through the past, present, and future at a spatial scale that varies with the characteristic speed of the animal.

    MCM2–7-dependent cohesin loading during S phase promotes sister-chromatid cohesion

    Ge Zheng, Mohammed Kanchwala ... Hongtao Yu
    Systematic analyses of DNA replication machinery components in human cells reveal a requirement of MCM-dependent de novo loading or mobilization of cohesin at replication forks in establishing sister-chromatid cohesion.

    Peripheral sensory coding through oscillatory synchrony in weakly electric fish

    Christa A Baker, Kevin R Huck, Bruce A Carlson
    Sensory receptors encode stimuli by transiently synchronizing ongoing electrical oscillations, conferring enhanced sensitivity to communication signals produced by large groups of conspecifics.

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

    Justin Losacco, Daniel Ramirez-Gordillo ... Diego Restrepo
    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.

    Independent theta phase coding accounts for CA1 population sequences and enables flexible remapping

    Angus Chadwick, Mark CW van Rossum, Matthew F Nolan
    Independent coding without synaptic coordination explains complex sequences of population activity observed during theta states and maximizes the number of distinct environments that can be encoded through population theta sequences.

    Decoding the physical principles of two-component biomolecular phase separation

    Yaojun Zhang, Bin Xu ... Ned S Wingreen
    Phase separation of two-component multivalent systems is suppressed at rational polymer stoichiometries, suggesting possible cellular strategies for regulating the formation and function of biomolecular condensates.

    Firing rate adaptation affords place cell theta sweeps, phase precession, and procession

    Tianhao Chu, Zilong Ji ... Si Wu
    Adaptation within a continuous attractor neural network explains theta phase precession and procession, providing insight into the neural mechanism of theta phase coding in the hippocampus.
    1. Neuroscience

    Phase-tuned neuronal firing encodes human contextual representations for navigational goals

    Andrew J Watrous, Jonathan Miller ... Joshua Jacobs
    Prospective navigational goals are represented by single neuron firing rates and firing relative to slow oscillatory phase (phase coding) in the human medial temporal lobe.
