    Flexible theta sequence compression mediated via phase precessing interneurons

    Angus Chadwick et al.
    A new model for phase precession accounts for theta sequence generation, suggests critical roles for interneurons, and predicts circuit properties to optimise memory storage.
    1. Neuroscience

    Distinct neural mechanisms underlie the success, precision, and vividness of episodic memory

    Franziska R Richter et al.
    Combining fMRI with continuous model-based measures of retrieval enables the behavioral and neural dissociation of multiple components of episodic memory.

    Reward-based training of recurrent neural networks for cognitive and value-based tasks

    H Francis Song et al.
    A two-part neural network models reward-based training and provides a unified framework in which to study diverse computations that can be compared to electrophysiological recordings from behaving animals.

    Cortico-hippocampal network connections support the multidimensional quality of episodic memory

    Rose A Cooper, Maureen Ritchey
    Enhanced hippocampal-cortical network communication during memory retrieval flexibly tracks the quality and content of memories for complex past events.

    Distinct roles of visual, parietal, and frontal motor cortices in memory-guided sensorimotor decisions

    Michael J Goard et al.
    Visual, parietal, and frontal motor cortices play distinct and necessary roles in mapping sensory features to future motor action.

    Cerebellar involvement in an evidence-accumulation decision-making task

    Ben Deverett et al.
    In a new evidence-accumulation decision-making task, activity of the lateral posterior cerebellum is necessary for accurate performance, and somatic and dendritic activity in Purkinje cells contains choice/evidence and error-related information.

    Human subthalamic nucleus activity during non-motor decision making

    Baltazar A Zavala et al.
    Intraoperative human brain recordings during a memory task reveal that when participants inhibit memory formation, the subthalamic nucleus shows higher beta power and beta coherence with areas of the lateral cortex implicated in memory processing.

    Adaptive learning and decision-making under uncertainty by metaplastic synapses guided by a surprise detection system

    Kiyohito Iigaya
    Computational modeling offers an explanation for why animals learn more quickly or slowly when their environment becomes more variable or stable.
    1. Neuroscience

    Testing sensory evidence against mnemonic templates

    Nicholas E Myers et al.
    Visual search templates are reactivated only temporarily to act as input filters for target detection.
    1. Neuroscience

    Offline replay supports planning in human reinforcement learning

    Ida Momennejad et al.
    fMRI evidence for off-task replay predicts subsequent replanning behavior in humans, suggesting that learning from simulated experience during replay helps update past policies in reinforcement learning.
