Social relationships are integral to the behaviour of many mammalian species. Primates are unusual in that their social relationships are extensive within groups, which often contain many reproductively active males and females. Several hypotheses have been forwarded to explain the ultimate causation of primate sociality. While attention has focused on grooming as a proximate factor influencing social relationships, the neural basis of such behaviour has not been investigated in monkeys. This… Expand

TLDR
It is suggested that these two neuropeptide families may play different roles in the processes of social bonding in primates and non-primates, and that more experimental work will be needed to tease them apart. Expand
Cellular Mechanisms of Social Attachment
TLDR
It is hypothesize that oxytocin and vasopressin may be facilitating affiliation and social attachment in monogamous species by modulating these reward pathways. Expand
The brain opioid theory of social attachment: a review of the evidence
The psychology of close human relationships is increasingly well understood and our understanding of the neurobiology of the onset of pairbonding behaviour in a range of species has benefited fromExpand
Opiate receptor blockade in juvenile macaques: effect on affiliative interactions with their mothers and group companions
TLDR
The hypothesis that the offspring-mother attachment and other social bonds within the group have in common neural mediating mechanisms involving brain opioids supports the hypothesis that, at a neural level, the endogenous opioid peptides form a common substrate for different types of social attachments in primates. Expand
Brain opioid receptors in relation to stereotypies, inactivity, and housing in sows
TLDR
These results provide the first demonstration of a relationship between abnormal behavior in pigs and opioid receptor density, and help to clarify the links between behavioral responses and opioid action. Expand
Effects of opioid receptor blockade on the social behavior of rhesus monkeys living in large family groups.
Rhesus monkeys of 9 weeks, 48 weeks, 100 weeks, 150 weeks of age (young subjects), or mature parous females that were not lactating were given acute single doses of the opioid antagonist naloxoneExpand
Genes, brains and mammalian social bonds.
TLDR
How this has been achieved, what conserved mechanisms underpin social bonding, and what genetic and mechanistic changes have occurred in the evolution of social bonds are the issues addressed here. Expand
Variation in the β-endorphin, oxytocin, and dopamine receptor genes is associated with different dimensions of human sociality
TLDR
It is suggested that an overemphasis on one neuropeptide (oxytocin), combined with a failure to distinguish between different social domains, has obscured the complexity involved and the social importance of endorphins may have been underestimated. Expand
Opioid receptor blockade reduces maternal affect and social grooming in rhesus monkeys
TLDR
Seven lactating female rhesus macaques, housed in social groups, were administered with low doses of the opioid antagonist naloxone when their infants were 4, 6, 8, and 10 weeks old, interpreted in terms of possible interference of nAloxone with maternal affect. Expand
Endogenous opioids: do they modulate the rat pup's response to social isolation?
: Previous studies with several different species have suggested that opioids and their receptors are involved in the mediation of the infant's vocal response to social isolation. In the case of theExpand

β-Endorphin levels in the cerebrospinal fluid of male talapoin monkeys in social groups related to dominance status and the luteinizing hormone response to naloxone
TLDR
Findings show that an animal's rank in the social group in which it lives is strongly correlated with beta-endorphin levels in the cerebrospinal fluid, and with changes in the neuroendocrine response to opiate blockade, which may be responsible for the depressed levels of sexual behaviour and gonadal function observed in monkeys at the bottom of the hierarchy.

TLDR
How a monkey's neuro-endocrine system responds to the factors that shape and organize its society and determine its individual role in that society is described. Expand
Endogenous opioids and social behavior
TLDR
In young rats tested in social learning situations, morphine delays and naloxone hasten extinction, consistent with the proposition that brain opioids modulate social emotions and behaviors. Expand
Opiate antagonists stimulate affiliative behaviour in monkeys
TLDR
The behavioural changes reported for this primate support the view that positive affect arising from social bonds may be mediated by cerebral endorphin containing systems. Expand
Behavioural and endocrine effects of naltrexone in male talapoin monkeys
TLDR
The behavioural changes reported for this primate are in direct contrast to changes reported in rodents, while the hormonal changes, except for prolactin, are comparable to others reported. Expand
The biology of social attachments: opiates alleviate separation distress.
TLDR
The possibility is entertained that brain opiates may function to control the intensity of emotions arising from social separation and parallels between the biological nature of narcotic addiction and the formation of social bonds are discussed. Expand
An autoradiographic map of (3H) diprenorphine binding in rat brain: Effects of social interaction
TLDR
Diprenorphine binding was higher in isolate-tested animals than socially-tested ones, suggesting that social interaction may promote endogenous brain opioid release. Expand
Effects of morphine and naloxone on separation distress and approach attachment: Evidence for opiate mediation of social affect
TLDR
The hypothesis that an endorphin-based addiction-like process may underlie the maintenance of social attachments, and that separation distress may reflect a state of endogenous "endorphin withdrawal", is supported. Expand
Interactions of pharmacological agents which alter biogenic amine metabolism and depression--an analysis of contributing factors within a primate model of depression.
TLDR
This paper has attempted to examine, in a nonhuman primate model of depression, the degree to which factors such as prior rearing condition, repeated peer separation, and housing environment can intact with the behavioral effects produced by biogenic amine depleting agents. Expand
Effects of imipramine treatment of separation-induced social disorders in rhesus monkeys.
TLDR
Two groups of young rhesus monkeys were subjected to repetitive peer separations, a procedure that has been shown to produce depressivelike reactions in infant monkeys, and the imipramine treatment yielded significant behavioral improvement in a form and with a time course similar to that seen when the drug is given clinically to human depressives.
