    Correlated signatures of social behavior in cerebellum and anterior cingulate cortex

    Sung Won Hur, Karen Safaryan ... Peyman Golshani
    Development of a novel open-source device, 'E-Scope,' to simultaneously record electrophysiology and calcium imaging in freely behaving animals, discovering co-modulation of the cerebellum, and anterior cingulate cortex during social interaction.

    A unifying mechanism governing inter-brain neural relationship during social interactions

    Wujie Zhang, Maimon C Rose, Michael M Yartsev
    Experiments and modeling suggest that a mechanism involving positive and negative feedback can explain the relationship between the neural activity of socially interacting bats.

    Genomic architecture and evolutionary antagonism drive allelic expression bias in the social supergene of red fire ants

    Carlos Martinez-Ruiz, Rodrigo Pracana ... Yannick Wurm
    Analyses of allelic- and socially-biased gene expression reveal that suppressed recombination causes most of the expression differences in the social supergene, with only few differences due to socially antagonistic selection.

    Habitat and social factors shape individual decisions and emergent group structure during baboon collective movement

    Ariana Strandburg-Peshkin, Damien R Farine ... Iain D Couzin
    For baboons on the move, habitat features across multiple spatial scales combine with social interactions to impact the movements of individuals, ultimately shaping the structure of the whole group.

    Stochastic social behavior coupled to COVID-19 dynamics leads to waves, plateaus, and an endemic state

    Alexei V Tkachenko, Sergei Maslov ... Nigel Goldenfeld
    Time-varying heterogeneous social activity explains transient suppression of epidemic waves followed by long plateaus and eventual transition towards the endemic state of an emergent pathogen, such as COVID-19.

    Neural network of social interaction observation in marmosets

    Justine C Cléry, Yuki Hori ... Stefan Everling
    The brain network associated with social interaction observation involves large part of the frontal cortex and parietal areas in marmosets.

    Different types of theta rhythmicity are induced by social and fearful stimuli in a network associated with social memory

    Alex Tendler, Shlomo Wagner
    Variations in the frequency of theta brain waves enable a single network of brain regions to generate appropriate responses to stimuli with different kinds of emotional value.

    Social-like responses are inducible in asocial Mexican cavefish despite the exhibition of strong repetitive behavior

    Motoko Iwashita, Masato Yoshizawa
    A new tracking method revealed the social-like interactions in the Mexican blind cavefish, which was thought to be evolutionarily lost, and also demonstrated its mammal-like antagonistic association between the social-like interaction and repetitive behavior.

    Functional heterogeneity of lymphocytic patterns in primary melanoma dissected through single-cell multiplexing

    Francesca Maria Bosisio, Asier Antoranz ... Joost van den Oord
    Multiplexing and digital analysis of melanoma tissue describe functionally the microenvironment associated with brisk/non-brisk infiltrates and expose the functional incongruences of this morphological classification currently in use for tumor-infiltrating lymphocytes.

    High-order social interactions in groups of mice

    Yair Shemesh, Yehezkel Sztainberg ... Elad Schneidman
    Tracking individual mice within a group makes it possible to quantify and model social behavior, and reveals that the behavior of the group goes beyond pairwise interactions, and is shaped by complex interactions between multiple individuals.
