Abstract:
:Novel environments induce a conflicting emotional approach-withdrawal state that triggers stress-related reactions. Social support through the presence of a highly familiar conspecific buffers the individual against such challenges. Although aversive events seem to be predominantly processed by the right hemisphere, this is still under debate and little is known about functional cerebral asymmetries in nonhuman primates during novelty stress, isolation and social buffering. Here we isolated adult marmoset monkeys in a new open-field arena or in their familiar home-cages to establish hemisphere activity and whether the pairmate's presence buffers the response. Monkeys socially isolated in either location had higher circulating cortisol levels than non-isolated marmosets, but different hemisphere activity patterns indicated by changes in baseline tympanic membrane temperatures (TMT). The bilateral increase in the monkeys that were isolated in the unfamiliar location may reflect an approach-withdrawal conflict. The left-sided increase in the home-cage isolation group was negatively related to cortisol release, this being potentially associated with a more proactive/approach-prone temperament. Interestingly, TMT and cortisol were unaltered when the pairmate was present. Thus, positive social interaction reduces the perceived intensity of the threat, alters hemisphere asymmetries and blocks the hormonal response to novelty stress, consistent with a buffering effect.
