    Different types of theta rhythmicity are induced by social and fearful stimuli in a network associated with social memory

    Alex Tendler, Shlomo Wagner
    Variations in the frequency of theta brain waves enable a single network of brain regions to generate appropriate responses to stimuli with different kinds of emotional value.

    Anatomical organization of presubicular head-direction circuits

    Patricia Preston-Ferrer, Stefano Coletta ... Andrea Burgalossi
    Presubicular head-direction circuits are cell-type specific, with long-range projections reaching the 'grid-cell area' medial entorhinal cortex.
    1. Neuroscience

    Different theta frameworks coexist in the rat hippocampus and are coordinated during memory-guided and novelty tasks

    Víctor J López-Madrona, Elena Pérez-Montoyo ... Santiago Canals
    Integration and segregation of information of memory and sensory in the hippocampus could be achieved by the coordination of distinct theta-gamma coding frameworks.

    Theta- and gamma-band oscillatory uncoupling in the macaque hippocampus

    Saman Abbaspoor, Ahmed T Hussin, Kari L Hoffman
    Oscillations that co-occur in hippocampal CA1 during exploration in the rodent are shown to segregate according to exploratory and sleep states in the primate.

    1. Neuroscience

    Theta oscillations locked to intended actions rhythmically modulate perception

    Alice Tomassini, Luca Ambrogioni ... Eric Maris
    Theta oscillations synchronize perception with the emerging motor intention in an automatic and task-independent way.
    1. Neuroscience

    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.
    1. Neuroscience

    Gamma activity accelerates during prefrontal development

    Sebastian H Bitzenhofer, Jastyn A Pöpplau, Ileana Hanganu-Opatz
    Maturation of inhibitory feedback accelerates gamma activity in the medial prefrontal cortex during development.
    1. Neuroscience

    mPFC spindle cycles organize sparse thalamic activation and recently active CA1 cells during non-REM sleep

    Carmen Varela, Matthew A Wilson
    Sleep spindles provide a temporal framework to organize the reactivation of behaviorally relevant CA1 cells and sparsely active cells in the limbic thalamus.
    1. Neuroscience

    Effects of visual inputs on neural dynamics for coding of location and running speed in medial entorhinal cortex

    Holger Dannenberg, Hallie Lazaro ... Michael E Hasselmo
    Spatial accuracy of grid cell firing correlates with the slope of the local field potential theta frequency vs. running speed relationship and integrates velocity signals over past time.
    1. Neuroscience

    Coherent theta activity in the medial and orbital frontal cortices encodes reward value

    Linda M Amarante, Mark Laubach
    The more you want it or the better it is, the stronger is medial frontal theta (paraphrased from a retweet of the preprint by Dr James Hyman).
