    Segregation of complex acoustic scenes based on temporal coherence

    Sundeep Teki, Maria Chait ... Timothy D Griffiths
    Experiments with realistic acoustic stimuli have revealed that humans distinguish salient sounds from background noise by integrating frequency and temporal information.

    Common resting brain dynamics indicate a possible mechanism underlying zolpidem response in severe brain injury

    Shawniqua T Williams, Mary M Conte ... Nicholas D Schiff
    The therapeutic effects of the sleeping pill zolpidem in patients with disorders of consciousness may be due to recruitment of brain cells idling in abnormally low-frequency brain waves.

    Rett-causing mutations reveal two domains critical for MeCP2 function and for toxicity in MECP2 duplication syndrome mice

    Laura Dean Heckman, Maria H Chahrour, Huda Y Zoghbi
    Transgenic mice with Rett-causing mutations in MeCP2 reveal that a basic cluster in the C-terminus of the protein binds DNA and that both the methyl-CpG binding domain and the transcriptional repression domain are necessary to elicit toxicity in MECP2 duplication syndrome.

    A role for descending auditory cortical projections in songbird vocal learning

    Yael Mandelblat-Cerf, Liora Las ... Michale S Fee
    Midbrain dopaminergic neurons and a cortex-like structure called the arcopallium form part of a circuit that enables young songbirds to compare their own song with a template stored in memory, and use any discrepancies to improve their performance.

    Human premotor areas parse sequences into their spatial and temporal features

    Katja Kornysheva, Jörn Diedrichsen
    Neuroimaging provides novel insights into how the motor system represents sequences of actions by automatically separating their spatial and temporal features for flexible skill production.

    Auditory selective attention is enhanced by a task-irrelevant temporally coherent visual stimulus in human listeners

    Ross K Maddox, Huriye Atilgan ... Adrian KC Lee
    Faced with multiple sources of sound, humans can better perceive all of a target sound's features when one of those features changes in time with a visual stimulus.
    1. Neuroscience

    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.
    1. Neuroscience

    The topography of frequency and time representation in primate auditory cortices

    Simon Baumann, Olivier Joly ... Timothy D Griffiths
    fMRI data from macaques suggest that sounds with similar temporal characteristics activate neighbouring regions of auditory cortex, giving rise to a topographic map broadly analogous to that for sound frequencies.

    Neural tuning matches frequency-dependent time differences between the ears

    Victor Benichoux, Bertrand Fontaine ... Romain Brette
    Complex properties of space-sensitive auditory neurons in cats mirror the complexity of acoustical environments.

    Speech encoding by coupled cortical theta and gamma oscillations

    Alexandre Hyafil, Lorenzo Fontolan ... Anne-Lise Giraud
    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.
