    It has been proposed that the amygdala is required for the familiarity aspect of item recognition. By studying the performance of monkeys with selective amygdala lesions on four converging memory paradigms, the authors demonstrate that the amygdala is not necessary for familiarity memory, but confirm its role in reward processing.

    The neural mechanisms underlying the effects of aging on executive functioning remain unclear. Here, the authors show neurons in the young mouse medial prefrontal cortex show cross-modal memory coding, however this declines in middle and old age, along with resting state functional connectivity in the region.

    How learning refines the coordinated activitity of neurons across multiple regions of the mouse cortex remains unclear. Here, the authors identified the emergence of cortical subnetworks during learning of a sensorimotor task.

    Social memory integrates past experiences into social interactions by distinguishing familiar from novel conspecifics. In this study, the authors delineated a role of the cerebellum in organizing the neural matrix required for social memory.

    Short-term memory deficits are associated with prefrontal cortex dysfunction in Alzheimer’s disease. Here, the authors assessed extratelencephalic projection (ET) neurons and found reduced ET neural activity in the medial prefrontal cortex (mPFC) and showed ET neurons received fewer cholinergic inputs from the basal forebrain in 5×FAD mice which led to object recognition memory deficits.

    Identical physical inputs can evoke non-identical percepts. Here, the authors investigate the sources of such variability and find that rats and humans, trained to judge tactile vibration strength, express a robust sequential effect that could be modeled as the trial-by-trial incorporation of sensory history.

    Epitranscriptomic modifications can regulate learning and memory. Here, the authors provide proteomic and functional analysis of N6-methyladenosine (m6A)-binding proteins in D. melanogaster and unveil behavioral and regulatory defects for m6A/Ythdf mutants.

    Synaptic plasticity ensures functionality during perturbations and enables memory formation. Here, the authors describe homeostatic functional and nano-modular active zone modifications for immediate and long-lasting enhancement of neurotransmitter release, and identify Unc13 as a presynaptic molecular target for homeostatic potentiation and learning.

    Memories formed around the same time are linked together by a shared temporal context. Here, the authors show that the ability to selectively retrieve distinct episodic memories formed close together in time is related to how quickly neural representations of temporal context change over time during encoding.

    Adaptation is thought to improve discrimination by pulling neural representations of similar stimuli farther apart. Here, the authors separately show that adaptation to a 3D shape class leads to better discrimination performance on similar shapes, and activity patterns diverge in object selective cortical areas.

    Short-term memories (STM) can become long-term memories when occurring alongside novel experiences. Here, the authors investigate the neural mechanisms behind such 'behavioural tagging' and find STM neural populations are preferentially incorporated into the ensembles encoding novel experiences.

    Lateral diffusion of receptors between synaptic and extrasynaptic sites is known to mediate plasticity. Hausrat et al. show that diffusion of α5-containing GABAAreceptors is controlled by phosphorylation of the extrasynaptic anchoring protein Radixin, and reveal a role for Radixin in learning and memory.
