    Fundamental bound on the persistence and capacity of short-term memory stored as graded persistent activity

    Onur Ozan Koyluoglu et al.
    A fundamental lower-bound on memory recall precision, which declines with storage duration and number of stored items, is derived, and human performance is shown to be well-fit by this theoretical bound.

    Phenotypic states become increasingly sensitive to perturbations near a bifurcation in a synthetic gene network

    Kevin Axelrod et al.
    Perturbations in the extracellular environment drive transitions from a highly stable memory state to an alternative phenotype in microorganisms.

    Transsynaptic mapping of Drosophila mushroom body output neurons

    Kristin M Scaplen et al.
    Transsynaptic mapping of the postsynaptic connections of mushroom body output neurons reveal both divergent and convergent projections allowing for multimodal integration prior to initiation of an output response.

    A theory of working memory without consciousness or sustained activity

    Darinka Trübutschek et al.
    Visual information can be maintained in non-conscious working memory for several seconds via short-term changes in synaptic weights.

    Place recognition using batlike sonar

    Dieter Vanderelst et al.
    Echolocating bats may recognize locations in the environment (and navigate to them) by remembering the specific echo signature of those locations.

    TRex, a fast multi-animal tracking system with markerless identification, and 2D estimation of posture and visual fields

    Tristan Walter, Iain D Couzin
    Being fast, memory efficient, easy to use, and with powerful integrated tools, TRex will lower barriers of entry into, and enable more ambitious approaches to, the quantitative study of behavior.

    Midbrain dopaminergic inputs gate amygdala intercalated cell clusters by distinct and cooperative mechanisms in male mice

    Ayla Aksoy-Aksel et al.
    Dopaminergic input shapes activity of specialized amygdala inhibitory cell clusters by ionotropic and metabotropic mechanisms that may enable their selection during distinct fear-related behavioral states.

    Shifting from fear to safety through deconditioning-update

    Bruno Popik et al.
    Deconditioning is a safe and efficient new approach to updating traumatic memories, in which fear memory is rewritten to a very low level in a long-lasting way.

    Task-induced functional brain connectivity mediates the relationship between striatal D2/3 receptors and working memory

    Matthew M Nour et al.
    Striatal dopamine 2/3 receptor (D2/3R) availability is related to working memory-induced functional connectivity changes in the default mode network, and this mediates the relationship between D2/3Rs and task performance.
