Brain Systems Underlying Fundamental Motivations of Human Social Conformity / 神经科学通报·英文版

From birth to adulthood, we often align our behaviors, attitudes, and opinions with a majority, a phenomenon known as social conformity. A seminal framework has proposed that conformity behaviors are mainly driven by three fundamental motives: a desire to gain more information to be accurate, to obtain social approval from others, and to maintain a favorable self-concept. Despite extensive interest in neuroimaging investigation of social conformity, the relationship between brain systems and these fundamental motivations has yet to be established. Here, we reviewed brain imaging findings of social conformity with a componential framework, aiming to reveal the neuropsychological substrates underlying different conformity motivations. First, information-seeking engages the evaluation of social information, information integration, and modification of task-related activity, corresponding to brain networks implicated in reward, cognitive control, and tasks at hand. Second, social acceptance involves the anticipation of social acceptance or rejection and mental state attribution, mediated by networks of reward, punishment, and mentalizing. Third, self-enhancement entails the excessive representation of positive self-related information and suppression of negative self-related information, ingroup favoritism and/or outgroup derogation, and elaborated mentalizing processes to the ingroup, supported by brain systems of reward, punishment, and mentalizing. Therefore, recent brain imaging studies have provided important insights into the fundamental motivations of social conformity in terms of component processes and brain mechanisms.

Clinical Study on Inhaling Laughing Gas Applied to Analgesic Labor / 中国医师杂志

Objective To discuss the effect of inhaling laughing gas and epidural anesthesia on reducing and relieving labor pain,and their influence on delivery process,mode and on newborns.Methods 190 cases were divided into three groups,group A: inhaling laughing gas group,group B:epidural anesthesia(CSEA) group and group C:without any analgesia,as control group. Observation and studing the degree of labor pain,delivery process,delivery ways,Apgar score,hemorrhage volume of delivery period,rate of postpartum hemorrhage among the three groups.Results Both the two kinds of analgesic methods(group A and group B) were effective in relieving labor pain.The method of inhaling laughing gas shorted the delivery process(P
