    Evolutionary stasis of the pseudoautosomal boundary in strepsirrhine primates

    Rylan Shearn et al.
    A larger non-recombining region in sexually dimorphic primates compared to sexually monomorphic ones supports the view that sexually antagonistic mutations have influenced the evolution of sex chromosomes in primates.

    A novel DNA primase-helicase pair encoded by SCCmec elements

    Aleksandra Bebel et al.
    SCCmec genomic islands encode a novel primase-helicase pair in which priming ability is conferred upon an A-family DNA polymerase domain by a novel protein cofactor.

    Associations between sounds and actions in early auditory cortex of nonhuman primates

    Ying Huang et al.
    Early auditory cortex of nonhuman primates represents associations between sounds and actions, in both spiking activity and local field potentials.

    Lipocalin-2 is an anorexigenic signal in primates

    Peristera-Ioanna Petropoulou et al.
    Lipocalin-2 is a strong predictor of hunger scores, reflects an anti-obesity response that is deregulated in severely obese subjects, and exerts an anorexigenic function with a conserved interspecies mechanism.

    A simple retinal mechanism contributes to perceptual interactions between rod- and cone-mediated responses in primates

    William N Grimes et al.
    A combination of physiological and perceptual experiments show that the responses of rod photoreceptors inhibit those of cones more than vice versa, and reveal both the site of the retinal interaction and the underlying mechanism.

    Macro-connectomics and microstructure predict dynamic plasticity patterns in the non-human primate brain

    Sean Froudist-Walsh et al.
    Brain recovery after injury can be predicted based on its activity and structure, which may allow us to understand why some brain injuries lead to permanent loss of cognitive function, while others do not.

    Targeted cortical reorganization using optogenetics in non-human primates

    Azadeh Yazdan-Shahmorad et al.
    Focal optogenetic stimulation strengthens functional connectivity between primary somatosensory and motor cortices in macaques, in a manner consistent with a Hebbian model of stimulus-driven plasticity.
    1. Neuroscience

    Mesoscopic-scale functional networks in the primate amygdala

    Jeremiah K Morrow et al.
    Multivariate data decomposition applied to local field potentials recorded from the primate amygdala revealed simultaneously active and functionally distinct networks, defined by anatomical boundaries between the nuclei.
    1. Neuroscience

    Cross-species cortical alignment identifies different types of anatomical reorganization in the primate temporal lobe

    Nicole Eichert et al.
    Cross-species alignment based on cortical myelin content can dissociate cortical expansion and relocation from changes in connectivity profiles in the temporal lobe of higher primates.
