对社会互动的微尺度神经动力学的研究尚未转化为对团队的组装、培训和评估的改进。这部分是由于团队活动中神经参与的规模，从个人大脑的毫秒振荡到团队的分钟/小时表现行为。我们使用中间神经动力学表征来显示医疗团队在管理模拟患者时遇到并解决不确定性时进入持续（50-100秒）神经动力学状态。第二个符号中的每一个都是将每个团队成员的脑电图（EEG）能力置于其他团队成员和任务的背景下开发出来的。这些表征是从具有19个记录电极的EEG耳机中获得的，每个记录电极为1-40 Hz频率。每个符号流中的信息估计是从每秒更新的香农熵的60秒移动窗口中计算出来的，从而提供了团队性能的定量神经动力学历史。当团队需要解决不确定性时，神经动力学组织随着任务需求的增加（即较低的熵）而波动。这些结果表明，中间神经动力学表征可以在团队合作的微观和宏观尺度之间提供定量的桥梁。
Research on the microscale neural dynamics of social interactions has yet to be translated into improvements in the assembly, training and evaluation of teams. This is partially due to the scale of neural involvements in team activities, spanning the millisecond oscillations in individual brains to the minutes/hours performance behaviors of the team. We have used intermediate neurodynamic representations to show that healthcare teams enter persistent (50-100 s) neurodynamic states when they encounter and resolve uncertainty while managing simulated patients. Each of the second symbols was developed situating the electroencephalogram (EEG) power of each team member in the contexts of those of other team members and the task. These representations were acquired from EEG headsets with 19 recording electrodes for each of the 1-40 Hz frequencies. Estimates of the information in each symbol stream were calculated from a 60 s moving window of Shannon entropy that was updated each second, providing a quantitative neurodynamic history of the team's performance. Neurodynamic organizations fluctuated with the task demands with increased organization (i.e., lower entropy) occurring when the team needed to resolve uncertainty. These results show that intermediate neurodynamic representations can provide a quantitative bridge between the micro and macro scales of teamwork.
