    Alterations in the amplitude and burst rate of beta oscillations impair reward-dependent motor learning in anxiety

    Sebastian Sporn, Thomas Hein, Maria Herrojo Ruiz
    State anxiety alters the dynamics of beta oscillations during reward-dependent motor learning, thereby impairing proper updating of motor predictions when learning in unstable environments.

    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.

    Beta oscillations and waves in motor cortex can be accounted for by the interplay of spatially structured connectivity and fluctuating inputs

    Ling Kang, Jonas Ranft, Vincent Hakim
    The observed activity of the motor cortex in space and time is reproduced by a model with a specific structure of the inputs to the motor cortex.

    Cortical beta oscillations map to shared brain networks modulated by dopamine

    Meera Chikermane, Liz Weerdmeester ... Wolf Julian Neumann
    Invasively recorded cortical beta oscillations form whole-brain structural and functional networks that are modulated by dopamine.

    Tracking the neurodevelopmental trajectory of beta band oscillations with optically pumped magnetometer-based magnetoencephalography

    Lukas Rier, Natalie Rhodes ... Matthew J Brookes
    The first neurodevelopmental study using a novel, wearable brain imaging system based on optically pumped magnetometers, shows age-related changes in neural oscillatory task responses and cortical functional connectivity.

    Right inferior frontal gyrus implements motor inhibitory control via beta-band oscillations in humans

    Michael Schaum, Edoardo Pinzuti ... Oliver Tüscher
    Response inhibition is initiated by the right inferior frontal gyrus (rIFG), and stopping performance is predicted by beta-band power as well as beta-band connectivity between rIFG and pre-supplementary motor area.

    Rhythmic coordination of hippocampal neurons during associative memory processing

    Lara M Rangel, Jon W Rueckemann ... Howard Eichenbaum
    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.

    The rate of transient beta frequency events predicts behavior across tasks and species

    Hyeyoung Shin, Robert Law ... Stephanie R Jones
    Across species, tasks and recording modalities, the rate of transient neocortical beta frequency (15-29Hz) events strongly predicts perceptual ability, providing fundamental mechanistic insight, with implications for tracking and manipulating brain dynamics.

    Auditory cortical alpha/beta desynchronization prioritizes the representation of memory items during a retention period

    Nathan Weisz, Nadine Gabriele Kraft, Gianpaolo Demarchi
    Top-down mediated decreases of beta activity in auditory cortex prior to a predictable distractor in an auditory working memory task is associated with increased representation of to-be-memorized information.

    Subthalamic beta-targeted neurofeedback speeds up movement initiation but increases tremor in Parkinsonian patients

    Shenghong He, Abteen Mostofi ... Huiling Tan
    Patients with Parkinson's disease can be trained to self-suppress beta bursts in subthalamic nucleus, which was accompanied by quicker reaction times when prompted to move but increased tremor.
