    Stimulus salience determines defensive behaviors elicited by aversively conditioned serial compound auditory stimuli

    Sarah Hersman et al.
    Perceived imminence of threat and resulting intensity of defensive responses during serial compound stimulus conditioning are determined by auditory stimulus salience, not cue sequence as recently reported.

    Cerebellar associative sensory learning defects in five mouse autism models

    Alexander D Kloth et al.
    Five mouse models of autism show deficits in delay eyeblink conditioning, a form of split-second sensory learning that involves the cerebellum, a frequent site of disruption in autistic brains.

    Persistent firing in LEC III neurons is differentially modulated by learning and aging

    Carmen Lin et al.
    Temporal associative learning enhances persistent firing in lateral entorhinal cortex (LEC) layer III neurons, while aging decreases persistent firing, leading to cognitive impairments.

    Instructed knowledge shapes feedback-driven aversive learning in striatum and orbitofrontal cortex, but not the amygdala

    Lauren Y Atlas et al.
    While the striatum and orbitofrontal cortex learn about threats through verbal warnings, the amygdala learns only from direct experience, suggesting that the amygdala forms part of a specialized threat detection system.

    Analysis of the immune response to sciatic nerve injury identifies efferocytosis as a key mechanism of nerve debridement

    Ashley L Kalinski et al.
    In the injured sciatic nerve, blood-derived monocytes and macrophages eat dying leukocytes, thereby contributing to nerve debridement and inflammation resolution, and this correlates with neuronal regeneration.

    Glucocorticoid receptor-mediated amygdalar metaplasticity underlies adaptive modulation of fear memory by stress

    Ran Inoue et al.
    Behavioral analyses and an optogenetic approach reveal an existence of GR-mediated metaplasticity in the LA and its link with adaptive fear response to auditory cues in a stressful condition.

    MeCP2 regulates Tet1-catalyzed demethylation, CTCF binding, and learning-dependent alternative splicing of the BDNF gene in Turtle

    Zhaoqing Zheng et al.
    Loss of MeCP2 function negatively impacts Tet1 and CTCF binding thereby negatively impacting learning-dependent DNA methylation and alternative splicing regulation.

    CA1 cell activity sequences emerge after reorganization of network correlation structure during associative learning

    Mehrab N Modi et al.
    As mice learn to associate events separated in time, neurons within the CA1 region of the hippocampus progressively reorganize their firing patterns, leading to a relay of cellular activity that bridges the two events.

    Social aversive generalization learning sharpens the tuning of visuocortical neurons to facial identity cues

    Yannik Stegmann et al.
    Measures of visuocortical activity during aversive generalization learning revealed sharpened representations of facial identity, reflecting inhibitory interactions between neuronal populations that represent facial features associated with threat versus safety.

    Distinct responses of Purkinje neurons and roles of simple spikes during associative motor learning in larval zebrafish

    Thomas C Harmon et al.
    Discrete classes of cerebellar Purkinje neurons show distinct changes in synaptic and spiking activity during motor learning, with simple spikes playing a shifting role during acquisition, expression, and maintenance of learned responses.
