    Disruption of the CRF1 receptor eliminates morphine-induced sociability deficits and firing of oxytocinergic neurons in male mice

    Alessandro Piccin, Anne-Emilie Allain ... Angelo Contarino
    Both genetic and pharmacological studies reveal an essential role for the CRF1 receptor in social behavior deficits induced by a single morphine administration in male, but not in female, mice.

    Functional gradients in the human lateral prefrontal cortex revealed by a comprehensive coordinate-based meta-analysis

    Majd Abdallah, Gaston E Zanitti ... Demian Wassermann
    A comprehensive meta-analysis of the neuroimaging literature reveals that the lateral prefrontal cortex of humans is mainly organized along its rostrocaudal axis according to a unimodal-to-transmodal pattern of network connectivity and a concrete-to-abstract axis of functional associations.

    Mountain gorillas maintain strong affiliative biases for maternal siblings despite high male reproductive skew and extensive exposure to paternal kin

    Nicholas M Grebe, Jean Paul Hirwa ... Stacy Rosenbaum
    Mountain gorillas, who live in close-knit social groups with siblings and non-siblings of both sexes throughout their lives, show distinct behavioral biases towards maternal versus paternal kin.

    Individual recognition and the ‘face inversion effect’ in medaka fish (Oryzias latipes)

    Mu-Yun Wang, Hideaki Takeuchi
    Medaka fish were able to use faces for individual recognition, and were slower to recognise inverted faces but not inverted non-face shapes.

    Pleiotropic effects of trisomy and pharmacologic modulation on structural, functional, molecular, and genetic systems in a Down syndrome mouse model

    Sergi Llambrich, Birger Tielemans ... Greetje Vande Velde
    Ts65dn mice exhibit structural, functional, molecular, and genetic alterations that are modulated but unrecovered by prenatal chronic GTE-EGCG, highlighting the importance of holistic studies to understand complex disorders and treatments.

    Distinct neural mechanisms underlie subjective and objective recollection and guide memory-based decision making

    Yana Fandakova, Elliott G Johnson, Simona Ghetti
    Neural substrates of objective vs. subjective memory states can be distinguished, including their role in supporting decisions aimed at optimizing performance.

    Oxytocin signaling in the medial amygdala is required for sex discrimination of social cues

    Shenqin Yao, Joseph Bergan ... Catherine Dulac
    Oxytocin signaling plays a critical role in a molecularly defined neuronal population of the Medial Amygdala to modulate the behavioral and physiological responses of male mice to females on a moment-to-moment basis.

    Natural forgetting reversibly modulates engram expression

    James D O'Leary, Rasmus Bruckner ... Tomás J Ryan
    Causal investigation of engram ensembles shows that natural forgetting is an active and reversible process driven by perceptual feedback, supporting the perspective of forgetting an adaptive function of the brain.

    CCR5 is a suppressor for cortical plasticity and hippocampal learning and memory

    Miou Zhou, Stuart Greenhill ... Alcino J Silva
    Repression of the G protein-coupled chemokine receptor CCR5 enhances MAPK/CREB signaling, long-term potentiation, somatosensory cortical plasticity, and learning and memory, while CCR5 over-activation by viral proteins may contribute to HIV-associated cognitive deficits.

    Oxytocin promotes coordinated out-group attack during intergroup conflict in humans

    Hejing Zhang, Jörg Gross ... Yina Ma
    Humans intranasally administered the neuropeptide oxytocin waste less and earn more spoils during intergroup conflict because oxytocin enables group members to better coordinate strategic attacking of out-groups.
