本文综述了在系统层面研究大脑内部活动最先进的技术。负责我们日常生活的神经活动是由大脑不同区域复杂的协调过程共同完成的。表面上,不同功能由具体的解剖结构所控制,然而事实上是通过内部大量相互连接的神经元和突触通路的动态网络来实现的。因此,从系统层面能更好地理解大脑的正常生理或病理状态。目前已有很多神经工程技术,但本文将重点关注三个领域:神经成像、神经接口和神经调控技术。神经成像能够帮助我们描绘大脑的结构和功能,这对理解正常和疾病状态下的神经系统功能至关重要。基于神经影像的知识,可以开发神经接口与神经系统进行交流,或者调控大脑的活动。这三个领域的研究对开发相关的仪器、设备及其应用很关键。在神经反馈的基础上,通过神经接口 (侵入式或非侵入式) 监测神经活动 (通过神经影像模式),以一定的刺激参数,调控和改变神经功能。总之,系统神经工程是指利用工程工具和技术来成像、解码和调控大脑,进一步理解大脑的正常功能及障碍修复。这些领域之间的相互交叉将引领系统神经工程的发展方向——发展神经技术,来增强对大脑整体功能和功能障碍的理解,以及对神经和精神障碍的干预。

This paper describes the Brain Computer Interface (BCI) system and the experiments to allow post-acute (<3 months) stroke patients to use electroencephalogram (EEG) to trigger neuromuscular electrical stimulation (NMES)-assisted extension of the wrist/fingers, which are essential pre-requisites for useful hand function. EEG was recorded while subjects performed motor imagery of their paretic limb, and then analyzed to determine the optimal frequency range within the -rhythm, with the greatest attenuation. Aided by visual feedback, subjects then trained to regulate their -rhythm EEG to operate the BCI to trigger NMES of the wrist/finger. 6 post-acute stroke patients successfully completed the training, with 4 able to learn to control and use the BCI to initiate NMES. This result is consistent with the reported BCI literacy rate of healthy subjects. Thereafter, without the loss of generality, the controller of the NMES is developed and is based on a model of the upper limb muscle (biceps/triceps) groups to determine the intensity of NMES required to flex or extend the forearm by a specific angle. The muscle model is based on a phenomenological approach, with parameters that are easily measured and conveniently implemented.

本文通过将对象跟踪形式化为序列决策过程,使控制理论与计算机视觉实现同步。强化学习(RL)智能体成功跟踪了两种液体之间的界面,这通常是化学、石化、冶金和石油行业中跟踪的关键变量。该方法使用少于100 张图像来创建环境,智能体无需专家知识即可从中生成自己的数据。与依赖大量参数的监督学习(SL)方法不同,这种方法需要的参数少得多,这自然降低了维护成本。除了经济性外,该智能体还对环境不确定性(如遮挡、强度变化和过度噪声)具有鲁棒性。在闭环控制情境下,基于界面位置的偏差被选作训练阶段的优化目标。该方法展示了RL方法在油砂行业中的实时对象跟踪应用。本文除了介绍界面跟踪问题外,还详细回顾了最有效的RL方法之一——actor-critic策略。

Ketamine exerts rapid and robust antidepressant properties in both animal models and depressed patients and tramadol possesses potential antidepressant effects. Brain-derived neurotrophic factor (BDNF) is an important biomarker for mood disorders and tropomyosin-related kinase B (TrkB) is a high affinity catalytic receptor for BDNF. We hypothesized that tramadol pretreatment might reinforce ketamine-elicited antidepressant effects with significant changes in hippocampal BDNF and TrkB levels in rats. Immobility time of rats receiving different treatment in the forced swimming test (FST) was observed. Levels of BDNF and TrkB in hippocampus were measured by enzyme linked immunosorbent assay. Results showed that tramadol (5 mg/kg) administrated alone neither elicited antidepressant effects nor altered BDNF or TrkB level. However, pretreatment with tramadol (5 mg/kg) enhanced the ketamine (10 mg/kg) -elicited antidepressant effects and upregulated the BDNF and TrkB levels in hippocampus. In conclusion, tramadol pretreatment reinforces the ketamine-elicited antidepressant effects, which is associated with the increased levels of BDNF and TrkB in rat hippocampus.

Brain-dead donors have become one of the main sources of organs for transplantation in Western countries. The quality of donor organs is closely related to the outcome of the transplantation. Experimental studies have confirmed the inferior graft survival of livers from brain-dead donors compared with those from living donors. Studies conducted in the past 10 years have shown that brain death is associated with effects on the decreased donor organ quality. However, whether the decrease in the viability of donor organs is caused by brain death or by the events before and after brain death remains uncertain. The purpose of this review is to introduce the advances and controversies regarding the influence of brain death on the viability of donor livers and to summarize the mechanisms of the different protective interventions for donor livers.
