    Multiple mechanisms link prestimulus neural oscillations to sensory responses

    Luca Iemi et al.
    Neural oscillations prior to a stimulus modulate the strength of early and late responses in opposite directions via distinct mechanisms.

    TrpV1 receptor activation rescues neuronal function and network gamma oscillations from Aβ-induced impairment in mouse hippocampus in vitro

    Hugo Balleza-Tapia et al.
    TrpV1 receptor activation rescues cognition-relevant network dynamics in mouse hippocampus in an acute Alzheimer disease model providing a novel therapeutic target.

    Neural oscillations as a signature of efficient coding in the presence of synaptic delays

    Matthew Chalk et al.
    Neural oscillations are a necessary consequence of efficient coding of sensory signals by a spiking neural network, limited by synaptic delays and noise.

    Beta band oscillations in motor cortex reflect neural population signals that delay movement onset

    Preeya Khanna, Jose M Carmena
    Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.
    1. Neuroscience

    Short-term synaptic dynamics control the activity phase of neurons in an oscillatory network

    Diana Martinez et al.
    The phase of a neuron in an oscillatory network can remain independent of network frequency when synaptic input strength and peak phase are adjusted in a frequency-dependent manner.
    1. Neuroscience

    Uniting functional network topology and oscillations in the fronto-parietal single unit network of behaving primates

    Benjamin Dann et al.
    Oscillatory synchronized hub neurons coordinate neural network activity across multiple brain areas.

    Shared rhythmic subcortical GABAergic input to the entorhinal cortex and presubiculum

    Tim James Viney et al.
    GABAergic parvalbumin-expressing 'orchid cells' of the medial septum selectively target GABAergic neurons in connected extra-hippocampal areas of the mouse, providing rhythmically bursting inhibitory input at the peak of hippocampal 5-12 Hz theta oscillatory cycles.
    1. Neuroscience

    On cross-frequency phase-phase coupling between theta and gamma oscillations in the hippocampus

    Robson Scheffer-Teixeira, Adriano BL Tort
    Phase-locking of hippocampal theta and gamma waves has been proposed to support memory formation, but an analysis using robust statistical methods finds no convincing evidence for the phenomenon.

    Mixed-mode oscillations and population bursting in the pre-Bötzinger complex

    Bartholomew J Bacak et al.
    Computational modeling reveals the mechanisms by which a diverse group of neurons in the brainstem generates rhythmic breathing in mammals.
    1. Neuroscience

    Synchronous beta rhythms of frontoparietal networks support only behaviorally relevant representations

    Evan G Antzoulatos, Earl K Miller
    Beta-band oscillations in the frontoparietal network may act as a filter of relevant versus irrelevant neural representations for the ongoing cognitive task.
