Social-interaction impairment in germ-free mice is associated with a markedly altered transcriptional response to social novelty in the amygdala, as characterised by replacement of upregulation of common stimulus-induced pathways with upregulation of the splicing machinery.

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.

The brain network associated with social interaction observation involves large part of the frontal cortex and parietal areas in marmosets.

Male and female mice react differently to social isolation but not to an acute physical stress.

Touch-mediated social interactions in human females elicited endogenous oxytocin and brain responses in a covariant manner, and these changes were modulated by the familiarity of the person delivering touch as well as the recent history of social interaction.

The critical period in the mouse olfactory system is defined by activity-dependent synapse formation induced by Semaphorin7A/PlexinC1 signaling in the neonatal glomeruli.

A set of sexually dimorphic neurons in female flies is part of a recurrent neural network and drives minutes-long persistent neural activity and persistent social behaviors.

Sensory enrichment creates a more columnar, less salt-and-pepper whisker map in somatosensory cortex, showing that impoverished experience contributes to intermixed tuning in rodent sensory maps.

The accuracy of the Hybrid Vocalization Localizer (HyVL) brings a revolution to the study of social vocalizations of rodents and other animals, where vocalizations often occur in close proximity, and will empower downstream analysis of sequence and semantic analyses.

4-Vinylanisole acts as maturation-accelerating pheromone to synchronize oocyte maturation of female adults in locusts.
