| Open AccessVisuo-frontal interactions during social learning in freely moving macaques
Behavioural tracking and wireless neural and eye-tracking recordings show that freely moving macaques learn to cooprate using visually guided signals along the visual-frontal cortical network.

| Open AccessPsychedelics reopen the social reward learning critical period
Behavioural electrophysiological and transcriptomic studies in mice show that psychedelic drugs reopen the social reward learning critical period and suggest that this involves reorganization of the extracellular matrix.

Frontal neurons driving competitive behaviour and ecology of social groups
Wireless tracking of neuronal activity in social groups of mice identifies neurons in the anterior cingulate that hold representations of an animal’s social rank and can influence the competitive effort that the animal exerts.

The neuropeptide Pth2 dynamically senses others via mechanosensation
In zebrafish, the expression levels of the neuropeptide Pth2 change as exposure to conspecifics is limited or increased, and these changes track the presence of individuals and group density through mechanical stimulations induced by the movements of other fish.

Social reward requires coordinated activity of nucleus accumbens oxytocin and serotonin
In male mice oxytocin acts as a social reinforcement signal within the nucleus accumbens (NAc) core, where it elicits a presynaptically expressed long-term depression (LTD) of excitatory synaptic transmission in medium spiny neurons; deletion of oxytocin receptors from the dorsal raphe nucleus, which provides serotonergic innervation of the NAc, and blockade of NAc serotonin 1B receptors both prevent oxytocin-induced LTD and social reward.

Spontaneous giving and calculated greed
Economic games are used to investigate the cognitive mechanisms underlying cooperative behaviour, and show that intuition supports cooperation in social dilemmas, whereas reflection can undermine these cooperative impulses.
