Social neuroscience and its potential contribution to psychiatry

Most mental disorders involve disruptions of normal social behavior. Social neuroscience is an interdisciplinary field devoted to understanding the biological systems underlying social processes and behavior, and the influence of the social environment on biological processes, health and well‐being. Research in this field has grown dramatically in recent years. Active areas of research include brain imaging studies in normal children and adults, animal models of social behavior, studies of stroke patients, imaging studies of psychiatric patients, and research on social determinants of peripheral neural, neuroendocrine and immunological processes. Although research in these areas is proceeding along largely independent trajectories, there is increasing evidence for connections across these trajectories. We focus here on the progress and potential of social neuroscience in psychiatry, including illustrative evidence for a rapid growth of neuroimaging and genetic studies of mental disorders. We also argue that neuroimaging and genetic research focused on specific component processes underlying social living is needed.     

Modeling socio-economic aspects of ecosystem management and biodiversity conservation

For successful ecosystem management and biodiversity conservation, in addition to ecological and evolutionary processes, we need to consider social and economic influences on the management target. Here, we introduce several theoretical models that address economic and social aspects of the human society which are closely related to ecosystem management. The first model analyzes economic decisions on the use of the common fishing ground in Jeju Island, Korea, by traditional divers and tourists. We observe that the way the number of tourists increases with the availability of resources strongly influences how benefits are distributed among fishing ground stakeholders. The second model discusses activities that raise public awareness about biodiversity, which will help maintain public support for conservation in the future. Based on control theory, we derive the optimal investment in these activities to maximize the long-term quality of the conservation target. The third model analyzes punishment scheme as a mechanism to enforce people to follow the regulation on the use of common resource. An important aspect of successful management is “graduated punishment”, in which the severity of the punishment applied to deviators gradually increases with the amount of harm caused by deviation from the rule. We show that graduated punishment is the most efficient way to ensure cooperation when evaluation errors are unavoidable and when people are heterogeneous with respect to the sensitivity to utility differences. We conclude that socio-economic aspects related to ecosystem management are promising research foci of theoretical ecology.     

Haloperidol treatment at pre-exposure phase reduces the disturbance of latent inhibition in rats with neonatal ventral hippocampus lesions

Animals with neonatal ventral hippocampal lesions develop during or after adolescence abnormal behaviors related to schizophrenia such as anxiety and latent inhibition disruption. The aim of this study was to test whether haloperidol injection prior to pre-exposure session in the latent inhibition test would facilitate latent inhibition.

住院精神分裂症患者生活质量调查及与认知功能和社会支持的关系分析

摘要 目的：调查住院精神分裂症患者生活质量情况,并分析生活质量与认知功能和社会支持的关系。方法：本次研究为回顾性分析,将2019年1月-2020年10月期间于我院住院的精神分裂症患者225例纳为病例组。通过宣传招募健康志愿者200例作为对照组。对比两组生活质量、社会支持评分和认知功能,住院精神分裂症患者生活质量的影响因素采用单因素和多因素Logistic回归分析。住院精神分裂症患者生活质量与认知功能和社会支持的关系采用Pearson 相关性分析。结果：病例组的健康状况调查问卷（SF-36）评分、社会支持评定量表（SSRS）评分均低于对照组（P<0.05）。威斯康星卡片分类测验（WCST）结果显示,病例组的错误应答数高于对照组,正确应答数低于对照组（P<0.05）,Stroop色词测验结果显示,病例数正确数低于对照组,错误数高于对照组（P<0.05）。Pearson相关性分析结果显示,住院精神分裂症患者SF-36评分与SSRS评分呈正相关（P<0.05）。住院精神分裂症患者生活质量与文化程度、性别、年龄、病程、药物治疗、住院时间情况有关（P<0.05）。多因素Logistic回归分析结果显示,年龄、病程、住院时间、药物治疗情况为影响住院精神分裂症患者生活质量的危险因素（P<0.05）。结论：住院精神分裂症患者的生活质量低于健康人群,影响其生活质量的因素主要包括社会支持以及患者的年龄、病程、住院时间、药物治疗情况。     

耐多药肺结核患者心理健康状况调查及与应对方式、社会支持的相关性研究

摘要 目的：探讨耐多药肺结核患者心理健康状况的影响因素,分析其及与应对方式、社会支持的相关性。方法：选择2018年4月至2020年5月我院诊治的101例耐多药肺结核患者作为观察组,选择同期99例敏感肺结核患者作为对照组。两组均测评症状自评量表-90(SCL-90)评分、医学应对问卷(MCMQ)评分以及社会支持评定量表(SSRS)评分,分析SCL-90总评分与MCMQ各因子评分、SSRS总评分的相关性,采用Logistic回归模型分析心理健康状况的影响因素。结果：与对照组相比,观察组的躯体化、人际关系、抑郁、焦虑、敌对性、恐怖和精神病性评分以及总评分明显提高（P<0.05）。与对照组相比,观察组的面对评分、客观支持、主观支持、支持利用度评分以及总评分均降低（P<0.05）。Pearson相关性分析显示,SCL-90总评分与MCMQ评分中的回避和屈服评分呈正相关性（r=0.386、0.311,均P<0.05）,SCL-90总评分与SSRS总评分呈负相关（r=-0.332,P<0.05）。多因素Logistic回归分析显示,经济状况差、躯体健康状况差、病情严重、睡眠质量差和生活满意度低是耐多药肺结核患者心理健康不良的独立危险因素（P<0.05）。结论：耐多药肺结核患者心理健康状况差,应对方式选择面对较少,总体社会支持水平较低,患者的心理健康状况与应对方式、社会支持存在一定的相关性。在提供躯体性治疗的基础上,应结合患者的心理健康状况及相关危险因素给予适当干预。     

Comparison of social interaction and neural activation in the main olfactory bulb and the accessory olfactory bulb between Microtus mandarinus and Microtus fortis

To gain insight into the function of AOB and MOB during different social interaction and in different vole species,the behaviors and neural activation of the olfactory bulbs in social interactions of mandarin voles Microtus mandarinus and reed voles Microtus fortis were compared in the present research.Mandarin voles spent significantly more time attacking and sniffing their opponents and sniffing sawdust than reed voles.During same sex encounters,mandarin voles attacked their opponents for a significantly ...     

Novel modulators for body weight changes induced by fasting and re-feeding in mice

Catch-up weight gain after malnutrition is a risk factor for metabolic syndrome. Here we show that social isolation enhanced fasting-induced weight loss and suppressed weight gain induced by re-feeding for 6 days following a 24-h fast in prepubertal wild-type mice. These effects of social isolation on weight gain were not associated with significant changes in daily average food consumption. Under the same housing condition, genetic deletion of β-endorphin reduced the fasting-induced weight loss and enhanced the re-feeding-induced weight gain in prepubertal mice. These effects of social isolation or genetic deletion of β-endorphin on these weight changes were attenuated and reversed in postpubertal mice. Moreover, genetic deletion of β-endorphin attenuated these effects of social isolation on the catch-up weight gain in prepubertal mice and reversed them in postpubertal mice. Thus, social isolation, endogenous β-endorphin, and age can be novel modulators for body weight changes induced by fasting and re-feeding in mice.     

棕色田鼠的配偶选择和相关特征

为了确定野外生态研究中对棕色田鼠婚配制度为单配制的预测,在实验室观察记录了棕色田鼠的配偶选择箱内对配偶鼠（与选择鼠交配刚生过仔,雌鼠产后动情）与陌生鼠、熟悉鼠（雌雄田鼠山居一段时间后,开始进行交配）与陌生鼠的选择,发现棕色田鼠访问、追逐、嗅闻、爬胯配偶鼠和熟悉鼠以及与配偶鼠和熟悉鼠交配和相伴的时间明显地多于对 陌生鼠,而且攻击陌生鼠的时间明显多于配偶鼠和熟悉鼠（Wilcoxon检验,P＜0.05）。结果表明：雌雄棕色田鼠特异性地选择配偶鼠和熟悉鼠,对陌生鼠表现出较多的排斥,从而在配偶选择上呈现单配制特征。通过统计计算棕色田鼠社会组织特征和室内的个体形态、幼仔发育、交配行为、双亲育幼行为、社交倾向等参数,然后把这些参数和婚配制度较明确的草原田鼠、松田鼠、山地田鼠、草甸田鼠的相关数据进行比较,发现它与多配制种类差异较大,而与单配制的田鼠各类相似,通过以上实验分析结果推断棕色田鼠的婚配制度可能呈单配制,和野外生态研究的推测相一致。     

Behavioral responses of an infant gorilla to maternal separation in a captive social group of lowland gorillas (Gorilla gorilla gorilla)

The present report describes behavioral reactions of a 33-month-old female infant gorilla to maternal separation in a captive social group whose composition is similar to that of wild groups. The infant gorilla responded differently to two types of maternal separation. When she remained alone for a few hours, she cried repeatedly and moved restlessly, indicating protest. Upon reunion and also for a few days thereafter, an intensification of the mother-infant relationship occurred. On the other hand, when she was separated from her mother but remained with the other group members for nine days, she did not display any behaviors that could be characterized as protest, but rather showed clear behavioral depression. During the 9-day separation period, she hardly played with other group members but she developed affiliative relationships with the leading male. After the reunion from the 9-day separation, she spent as much time near her mother as before separation and played with other infants at a level similar to that before separation, while she sometimes displayed behavioral patterns demanding the maintenance of physical contact with her mother. The present findings are compared with other reports in great apes and human children.
