    Development of schemas revealed by prior experience and NMDA receptor knock-out

    George Dragoi, Susumu Tonegawa
    Novel spatial representations by hippocampal cellular assemblies develop on the framework of preconfigured hippocampal networks whose homeostatic synaptic reorganization is accelerated by prior experience and CA3 NMDAR-dependent plasticity.

    Neural dynamics of visual ambiguity resolution by perceptual prior

    Matthew W Flounders, Carlos González-García ... Biyu J He
    Neural dynamics during prior experience-guided visual ambiguity resolution reveal early stimulus-feature processing and late content-specific recognition processing involving large-scale brain networks.
    1. Neuroscience

    Experience, circuit dynamics, and forebrain recruitment in larval zebrafish prey capture

    Claire S Oldfield, Irene Grossrubatscher ... Ehud Y Isacoff
    Experience strengthens hunting in larval zebrafish by recruiting the forebrain to increase the prey-evoked activity in visual areas and trigger motor activity and prey capture.
    1. Neuroscience

    Reaction times can reflect habits rather than computations

    Aaron L Wong, Jeff Goldsmith ... John W Krakauer
    Although reaction times are often assumed to reflect the time required to select and prepare a movement, they can be strongly influenced by prior experience.
    1. Neuroscience

    Content-specific activity in frontoparietal and default-mode networks during prior-guided visual perception

    Carlos González-García, Matthew W Flounders ... Biyu J He
    Prior experience alters content-specific neural representations of visual input in frontoparietal and default-mode networks.

    The periaqueductal gray and Bayesian integration in placebo analgesia

    Arvina Grahl, Selim Onat, Christian Büchel
    Bayesian integration is able to predict placebo treatment outcomes by focusing especially on the influence of the precision of expectations.
    1. Neuroscience

    Emotional vocalizations alter behaviors and neurochemical release into the amygdala

    Zahra Ghasemahmad, Aaron Mrvelj ... Jeffrey J Wenstrup
    The modulatory neurochemicals acetylcholine and dopamine are released differentially into the basolateral amygdala depending on the emotional content of vocalizations and the sex, hormonal state, and experience of listening animals.

    Intergenerational effects of early adversity on survival in wild baboons

    Matthew N Zipple, Elizabeth A Archie ... Susan C Alberts
    In wild baboons, a female's adverse early experiences can influence her offspring's survival years after the original adversity was experienced.

    Learning steers the ontogeny of an efficient hunting sequence in zebrafish larvae

    Konstantinos Lagogiannis, Giovanni Diana, Martin P Meyer
    Early hunting experience modifies the kinematics of hunting in larval zebrafish to increase the probability of successfully capturing live prey.
    1. Neuroscience

    Accelerated redevelopment of vocal skills is preceded by lasting reorganization of the song motor circuitry

    Michiel Vellema, Mariana Diales Rocha ... Manfred Gahr
    The ability to quickly re-acquire a previously lost motor skill is associated with lasting synaptic changes in the brain circuit that controls that motor skill.
