Social isolation prevents the development of individual face recognition in paper wasps
Animal Behaviour, 2019Co-Authors: Elizabeth A. Tibbetts, Erica Desjardins, Nora Kou, Laurel WellmanAbstract:Much work has shown that Social isolation has lasting negative effects on adult Social interactions, but less is known about precisely how and why isolation alters Social behaviour. One way isolation may alter Social behaviour is by interfering with the development of effective communication. Here, we test how Social isolation influences individual recognition, a key aspect of Social communication in Polistes fuscatus paper wasps. Polistes fuscatus reared in a typical Social environment learn and remember the unique faces of conspecifics during Social interactions. Typical P. fuscatus use individual face recognition to minimize conflict and stabilize Social interactions. As wasps are adept face learners, they also readily learn to discriminate between wasp face images during training. Here, we show that Social isolation had dramatic effects on recognition. We isolated wasps for 6 days after eclosion from pupation, then tested them for face recognition in Social and nonSocial contexts. Isolated wasps did not learn and remember other individuals during Social interactions. Furthermore, isolated wasps did not learn to discriminate between wasp face images during training. Therefore, Social Experience with conspecifics is essential for the development of individual recognition and face learning in paper wasps. Many aspects of wasp behaviour develop rapidly with little Experience required. However, complex Social interactions like individual recognition require Social Experience with conspecifics.

Social isolation during the critical period reduces synaptic and intrinsic excitability of a subtype of pyramidal cell in mouse prefrontal cortex
Cerebral Cortex, 2018Co-Authors: Kazuhiko Yamamuro, Michihiro Toritsuka, Manabu Makinodan, Gabriel Corfas, Hiroki Yoshino, Yoichi Ogawa, Masayuki Yamashita, Toshifumi KishimotoAbstract:Juvenile Social Experience is crucial for the functional development of forebrain regions, especially the prefrontal cortex (PFC). We previously reported that Social isolation for 2 weeks after weaning induces prefrontal cortex dysfunction and hypomyelination. However, the effect of Social isolation on physiological properties of PFC neuronal circuit remained unknown. Since hypomyelination due to isolation is prominent in deep-layer of medial PFC (mPFC), we focused on 2 types of Layer-5 pyramidal cells in the mPFC: prominent h-current (PH) cells and nonprominent h-current (non-PH) cells. We found that a 2-week Social isolation after weaning leads to a specific deterioration in action potential properties and reduction in excitatory synaptic inputs in PH cells. The effects of Social isolation on PH cells, which involve reduction in functional glutamatergic synapses and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid/N-methyl-d-aspartate charge ratio, are specific to the 2 weeks after weaning and to the mPFC. We conclude that juvenile Social Experience plays crucial roles in the functional development in a subtype of Layer-5 pyramidal cells in the mPFC. Since these neurons project to subcortical structures, a deficit in Social Experience during the critical period may result in immature neural circuitry between mPFC and subcortical targets.

Social Experience dependent myelination an implication for psychiatric disorders
Neural Plasticity, 2015Co-Authors: Michihiro Toritsuka, Manabu Makinodan, Toshifumi KishimotoAbstract:Myelination is one of the strategies to promote the conduction velocity of axons in order to adjust to evolving environment in vertebrates. It has been shown that myelin formation depends on genetic programing and Experience, including multiple factors, intracellular and extracellular molecules, and neuronal activities. Recently, accumulating studies have shown that myelination in the central nervous system changes more dynamically in response to neuronal activities and Experience than expected. Among Experiences, Social Experience-dependent myelination draws attention as one of the critical pathobiologies of psychiatric disorders. In this review, we summarize the mechanisms of neuronal activity-dependent and Social Experience-dependent myelination and discuss the contribution of Social Experience-dependent myelination to the pathology of psychiatric disorders.

Social Experience during adolescence influences how male zebra finches (Taeniopygia guttata) group with conspecifics
Behavioral Ecology and Sociobiology, 2014Co-Authors: Tim Ruploh, Hans-joachim Bischof, Nikolaus EngelhardtAbstract:Group-living animals rely on Social skills which ensure beneficial interaction and prevent harmful ones with conspecifics. In a previous experiment, we demonstrated that male zebra finches reared in groups during adolescence show consistently less courtship and aggressive behaviour as adults than pair-reared males. Here we tested whether such differences affect how they group with conspecifics, as an indicator of their Social integration. Zebra finches were kept in pairs (male–female or male–male) or mixed-sex groups (three males and three females) during adolescence and were introduced to an established group of unknown conspecifics during adulthood. Male courtship and aggressive behaviour were quantified directly after introduction to the group and 48 h later. At the same time, male position in relation to other birds and the number of birds in proximity were recorded. Males that grew up in a small mixed-sex group during adolescence spent more time within groups, were observed in bigger groups and lost less weight than males raised in pairs, indicating that an enriched Social environment during early development may facilitate Social integration. However, we observed no differences in courtship and aggressive behaviour that could predict the differences in grouping behaviour of pair- and group-reared males. We discuss alternative explanations for the difference in grouping and how to test these in future research.
