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

    Víctor J López-Madrona et al.
    Integration and segregation of information of memory and sensory in the hippocampus could be achieved by the coordination of distinct theta-gamma coding frameworks.

    Rhythmic coordination of hippocampal neurons during associative memory processing

    Lara M Rangel et al.
    Different rhythms uniquely contribute to task-related processing in the hippocampus, and changes in the rhythmic profile of the hippocampus reflect dynamic coordination of its cell activity.

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

    Angus Chadwick et al.
    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.

    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.

    Speech encoding by coupled cortical theta and gamma oscillations

    Alexandre Hyafil et al.
    Computational modelling shows that coupled theta and gamma oscillations in the auditory cortex can decompose speech into its syllabic constituents, and organize the neural spiking at faster timescale into a decodable format.

    Interneuronal mechanisms of hippocampal theta oscillations in a full-scale model of the rodent CA1 circuit

    Marianne J Bezaire et al.
    Spontaneous theta oscillations and interneuron-specific phase preferences emerge spontaneously in a full-scale model of the isolated hippocampal CA1 subfield, corroborating and extending recent experimental findings.

    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

    Theta oscillations locked to intended actions rhythmically modulate perception

    Alice Tomassini et al.
    Theta oscillations synchronize perception with the emerging motor intention in an automatic and task-independent way.
    1. Neuroscience

    Non-rhythmic head-direction cells in the parahippocampal region are not constrained by attractor network dynamics

    Olga Kornienko et al.
    Head-direction cells in the parahippocampal region can be divided into two functionally distinct classes that are differentially constrained by attractor network dynamics.
    1. Neuroscience

    Computational models of O-LM cells are recruited by low or high theta frequency inputs depending on h-channel distributions

    Vladislav Sekulić, Frances K Skinner
    The contribution of biophysical ion channels to neuron function can be predicted by taking advantage of an ongoing dialogue between model and experiment.
