    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.

    Activity in developing prefrontal cortex is shaped by sleep and sensory experience

    Lex J Gómez, James C Dooley, Mark S Blumberg
    Behavioral and neurophysiological recordings in infant rats reveal that sleep and sensory experience influence neural activity in prefrontal cortex, mirroring similar findings in developing sensorimotor cortex.

    Differential dopaminergic modulation of spontaneous cortico–subthalamic activity in Parkinson’s disease

    Abhinav Sharma, Diego Vidaurre ... Esther Florin
    Dopaminergic medication has differential effects on the discovered electrophysiological networks, which could be used to develop new electrical and pharmacological interventions in Parkinson’s disease.

    Frequency-specific neural signatures of perceptual content and perceptual stability

    Richard Hardstone, Matthew W Flounders ... Biyu J He
    While perceptual content is encoded in non-oscillatory activity in the slow cortical potential (<5 Hz) range, perceptual stability is predominantly influenced by the amplitude fluctuations of alpha (~10 Hz) and beta (~20 Hz) brain oscillations.

    Bayesian analysis of phase data in EEG and MEG

    Sydney Dimmock, Cian O'Donnell, Conor Houghton
    A Bayesian model of phase angles illustrates a novel approach to the analysis of phase coherence in frequency-tagged experiments.

    Analogue closed-loop optogenetic modulation of hippocampal pyramidal cells dissociates gamma frequency and amplitude

    Elizabeth Nicholson, Dmitry A Kuzmin ... Dimitri Michael Kullmann
    Neurons can synchronize, supporting flexible communication among brain areas; closed-loop optogenetics allows the frequency and power of population oscillations to be dissociated, providing a tool to interrogate how networks couple.
    1. Neuroscience

    A dynamic generative model can extract interpretable oscillatory components from multichannel neurophysiological recordings

    Proloy Das, Mingjian He, Patrick L Purdon
    Oscillation component analysis enables cognitive neuroscientists to summarize millisecond-precision high-dimensional neurophysiological recordings into a smaller set of oscillatory components through biophysically inspired generative modeling of neural oscillations.

    Detection of transient synchrony across oscillating receptors by the central electrosensory system of mormyrid fish

    Alejandro Vélez, Bruce A Carlson
    Building on previous work (Baker et al., 2015), further evidence is reported for a novel mechanism for sensory coding based on the detection of oscillatory synchrony among peripheral receptors.

    MTL neurons phase-lock to human hippocampal theta

    Daniel R Schonhaut, Aditya M Rao ... Michael J Kahana
    Neural spiking throughout the MTL is synchronous with hippocampal theta phase during spatial memory and navigation experiments in humans, even after controlling for phase-coupling to local theta oscillations.

    Synchronization of oscillatory growth prepares fungal hyphae for fusion

    Valentin Wernet, Marius Kriegler ... Reinhard Fischer
    Fungal hyphae constantly undergo signal oscillations, comparable to a cell 'monologue' until they meet another hypha with which they then coordinate signal oscillations and transit into a cell-to-cell dialogue.
