    Hippocampal theta coordinates memory processing during visual exploration

    James E Kragel et al.
    Eye movements time-locked to retrieval and novelty during learning preferentially occur at distinct phases of hippocampal theta.

    One-shot learning and behavioral eligibility traces in sequential decision making

    Marco P Lehmann et al.
    Human learning relies on short-term memories (eligibility traces) which provide a mechanism to reinforce sequences of actions from a single reward (one-shot).

    Electrical and Ca2+ signaling in dendritic spines of substantia nigra dopaminergic neurons

    Travis A Hage et al.
    Dopaminergic cells uniquely receive input from a roughly equal mixture of synapses on dendritic spines and synapses formed directly on dendrites.
  1. Point of View: Mitigating the impact of conference and travel cancellations on researchers’ futures

    Tracey Weissgerber et al.
    As the scientific community adapts to new working conditions in response to the growing pandemic, early-career researchers recommend actions to help lessen the unintended consequences of canceled conferences.

    A molecular mechanism underlying gustatory memory trace for an association in the insular cortex

    Chinnakkaruppan Adaikkan, Kobi Rosenblum
    The role of CaMKII-GluA1 in the cortex in maintaining a given taste memory trace for an aversive association has been elucidated.

    A locally-blazed ant trail achieves efficient collective navigation despite limited information

    Ehud Fonio et al.
    Ants employ a new kind of trail to resolve group-level navigational difficulties in scenarios where the information available to individuals does not suffice.

    Travel fosters tool use in wild chimpanzees

    Thibaud Gruber et al.
    Travel has a major influence on tool use in wild chimpanzees, suggesting that tool use reduced travel costs during hominid evolution.

    Spontaneous neural synchrony links intrinsic spinal sensory and motor networks during unconsciousness

    Jacob Graves McPherson, Maria F Bandres
    Persistent, non-random sensorimotor connectivity reveals the capacity of intrinsic spinal networks to purposefully replay and modify learned patterns of neural transmission during unconsciousness.
    1. Neuroscience

    Distinct neuronal populations contribute to trace conditioning and extinction learning in the hippocampal CA1

    Rebecca A Mount et al.
    Large-scale imaging analysis of CA1 reveals that distinct neural networks are involved in trace conditioning versus extinction learning, shedding light on how the hippocampus encodes different types of memory.

    Phenotypic plasticity as an adaptation to a functional trade-off

    Xiao Yi, Antony M Dean
    A plastic behavior in Escherichia coli is enabled by a single amino acid replacement in adaption to changing environments.
